Those are the chambers, the bowl is the round area behind the valves.

 

Who are you responding to? I asked for the bowls, but he gave me the chambers with the valves installed, so I told him I needed a pic with the valves removed so that I can see down into the bowls...

 

the motown/accel intake is just a tad under a felpro 1206 gasket in Hight.
and just about the same 1206 in wide.

Motown No clean up Needed(Fantastic finnish in Runners) bolt on 1206 gasket
hight 2.041
wide 1.214

for the cost, fit, and finnish (wish it was polished). but the Fantastic mech work and fit. Im going to Keep, it.

BELOW: this is what Eliminators Look like, out of the Box..Note gasket is a Felpro 1206

 

Ok, I will grab a spring tool and pop the valves out of a cylinder.

So a Motown would be too big for these heads, but not for 195 Eliminators or are those Elims you posted bigger than 195s?

 

I posted pics of Eliminator 220's

Valves 2.100 and 1.65..(yes 2.100) just a tad bit bigger the 2.02s

 

 

Oh, and the valves had numbers on them: AFR 7204 (int) and AFR 7219 (exh). That confirms them as 2.02/1.60.

 

I was responding to woody80z28. Just letting him know the terminology in what I had assumed was a fairly friendly manner. I should have included a quote for clarity.

 

This is a great thread, I have been thinking of doing this myself and you all have provided so much information. Thank you. I look forward to more reading/discussion.

 

I just realized I missed something before. The Accel Super Ram intake like pictured here is about a 1206 port and too big for my heads?

 

the only accel intake pic is of a PRORAM not the SuperRam.

the Super Ram intake ports are smaller then the 1206 Gasket.

The ProRam, intake is for larger HP/RPM engs

 

The pro ram (singleplane) is a 1206. The superram is a TPI pizza box abortion.

One thing to note. I just bolted my throttle body on my hurricane and the linkage hits the fuel rail at part throttle, and it won't go wide open.

I've got to measure my hood but I don't think I can get away with a 1" spacer (which would be needed).

-- Joe

 

I'm glad you guys have your facts straight, this has been confusing for an EFI noob. haha

This is the used Accel setup I can get for a good price. But if it is a 1206 Pro Ram maybe it's not a good idea and the Edelbrock would be better.

 

Can I ask what Make/who makes the TB in that this Pic. Looking for one just like it...not one sorta like it....But.Just like it...Anybody?

Jeff

 

If you sell your afr heads just buy a 1206 head. If you can get the pro ram for good price go for it. I really dont think the step down in port size is gonna kill all performance in case you end up using the 1205 heads. Its not like you are looking to set hp per cube records on the build. You can make good power still. If the heads sell you are in good shape

 

Sold the heads and bought the Accel setup between yesterday & today. From the seller it sounds like the Accel is a 1205, but I will know for sure once it gets here. That will influence my head choice.

 

The only concern I'd have is the cost of the 1206 heads. The AFR 210 with 1206 ports is cheaper than the 195s with comp ports, but I don't think 210s on his 355 is going to be a good match.

The 195s with comp ports will have better velocity and probably be better head on a street 355.

-- Joe

 

Yeah, the comp ports are big money, too. Once the Accel manifold is in my hands I can measure the ports and see. If it's a 1205 I'm golden with a regular 195 head. Which from the sounds of it would be great for a 383 too. I'd love to go Dart SHP 400ci+, but by that time you are talking a pretty big budget.

 

you can do a 427/434 small block for under $3500 today (shipped any place usa)
thats all set up to bolt parts onto also.

(thats with a aftermarket block also)

 

This is for the short block I assume? Assembled? That is much cheaper than I anticipated. I already have a 4-bolt roller 350 block out of a TBI truck, but that will take some cash to turn in to a 383 also.

Where do I find such a 427? haha

 

Depends on what you get and who does it. My shp block 401 with callies rotating assembly was 4600 shipped. Not assembled but included all bearings bolts studs etc needed. Block itself is 1800 fully machine and blue printed, not straight from summit. Even tho its advertised as machined they need cleanup and bored or honed to your pistons and clearances checked with your crank.

Getting all that for less than 4k is impressive. Cnc motorsports is doing that at 3,600 with eagle parts and dart shp block. Thats best deal ive seen but dont know their quality. Seems good tho

 

Can't stress that more! Every piston requires different side clearance, deck heights vary.

The SHP blocks are a good deal, but at minimum they will need a hone, and that is assuming your assembled piston height works with the stock deck height.

-- Joe

 

I found a setup from Skip White for 3250 unassembled. Would still need fasteners though. Going to give them a call. Cause I'm figuring almost $2500 just for a forged 383 short block.

 

Yeah for alittle more, basically price of a block you can have huge inches. If you did have a good core factory block you'd be in for cost of a 383 basically. Forged parts all cost same wether its 3.48" stroke or 4". Might as well take cubes.

 

I called them and they will do it for $3100 shipped using my SFI flywheel & balancer. This really has me thinking.

What does a used 400hp 355 go for these days? And a virgin 350 4-bolt roller. haha

 

50% of part value..

I don't know many people that will buy a used engine. Might last a minute or a mile.

-- Joe

 

What is in it for parts?

My crank alone was $600...

-- Joe

 

http://www.wheelerpowerproducts.com/...vy-427-sb.aspx

this is one place. the 427 Above is in there SportsMen Class

and below is a 434 in there Comp Class eng right at $3999
shipping was like $200 (this is what i did.but in 427) did it when it was on sale upped H Beam rods and a few other thigs. was still under $4000 shipped to me

http://www.wheelerpowerproducts.com/...vy-434-sb.aspx

you can spend $$ on parts cranks $600 to $1500.
try a set of Titaneum (spelling) Rods ya want to talk Money

this is the eng i had done. but with Better Heads. and EFI.
http://www.wheelerpowerproducts.com/...ace-crate.aspx

3 weeks to my Door


4 bolt,front to back (not just the midl ones)



then ya drop another $4000 for the top end.and thats about 75% for the eng cost.
after all, I always wanted a 427 Camaro (so i did one My Self!)

 

Nothing special, it's just matched well. Stock replacement crank & rods, forged TRW flat tops, Vortecs clearanced to .500, Comp 280H cam w/ double roller chain, RPM AirGap intake, 750 Eddy carb, MSD HEI distributor.

I'm gonna list it on craigslist and see what happens. I never thought I'd get the money back out of my old AFR heads but I did.

 

I've gotten lots of tire kickers on craigslist for my 355. Everyone wants it really bad but doesn't want to pay. I'm asking $2000 to start carb to pan with fuel pump and distributor and AN lines. I've got all winter, so I'm in no hurry.

 

When you do buy a new longblock, make sure you get a forged crank. Even those scat 900 cast cranks work fine on 500~ hp cars with AUTOMATICS, but a good hard launch with a manual will window the block.

-- Joe

 

Yeah, the short block I'm looking is fully forged. No sense in not going forged if building from scratch the way I see it.

I know how rough a manual trans is. The 355 killed my stock 8.5" 10-bolt on a clutch dump at the track.

 

The used EFI kit came in today, I'm psyched. Everything looks good. And my low-pro Eddy TB linkage clears the rails with no spacer. Drop base also clears everything fine. I had to use a 1" spacer on the drop base to clear my fuel inlet on the carb, and the TB is 3/4" shorter than the carb, so I might even end up with more hood clearance.






Current setup with the airgap & carb:

 

If you needed a spacer perfect time for a nitrous plate

 

So I measured the intake ports with a ruler since my calipers were at work and I got almost exactly 1-3/16 x 1-15/16 (1.1875 x 1.9375) which is quite a bit smaller than 1206. I also noticed the Hurricane in the ebay listing is listed at 1.11 x 1.80 (left small for porting). Is that accurate? If so I might sell the Accel manifold and run the Hurricane with the Accel electronics.

 

I thought you needed the small port? Did you sell the old afr's?

 

If you look at post #30 by me, I put a 1206 over the port and traced it. It is just a little bit under a 1206, but so is the AFR 'comp ports'.

https://www.thirdgen.org/forums/post...10-post30.html

It's larger than a 1205.

I purchased this one:

http://www.ebay.com/itm/SBC-Chevy-Hi...2cdd04&vxp=mtr

I think the dimensions listed are not quite right. If you do get one, keep in mind you will need a fuel rail kit.

-- Joe

 

Hey Joe, I saw your post, but it's hard to see in that pic. Did you happen to pull measurements when you did it? I know I will need the rails - they are like $60 from "procompoverstock" on ebay.
http://www.ebay.com/itm/SMALL-BLOCK-...a7c56d&vxp=mtr

Orr, I sold the old AFRs because I really want Eliminators. And if I go 421ci, the 1204 Accel will be pretty small.

 

If you go 421 you better get the 220's atleast

 

Yeah, that's still an "if." I've gotten lots of calls on my 355, but they're tire kickers.

I called KMJ and had them measure a manifold and their listing online is way off as you expected, Joe. 1.2 x 1.95 is what they told me. That would still be a 1204 though, and not even a 1205.

I almost want to order one and see for myself.

 

Does theirs say "procomp" on the front? Mine did.. I wonder if their is more than one casting...

-- Joe

 

No it doesn't...that was another thing I noticed. Maybe that is the difference.

http://www.ebay.com/itm/SBC-CHEVY-Hi...item4cf76cd16c




This manifold has longer runners and just looks a lot better than the Accel. The Accel has bosses for Vortec holes and what I assume is EGR in the center bolts. And the MAT up front is ugly. Small details, but being a designer it drives me nuts. haha I like a nice, clean slate.

 

I bet you a six pack the picture is wrong Look at the description, says you are getting procomp stock.

Overall I like mine. My only complaint was I had to get a 1/2" spacer because the linkage on my throttle body crashed into the fuel rail. Although, I'm running a holley throttle body and the linkage was designed by an ape.


-- Joe

 

I would convert to a plastic style mat sensor and put it in the intake tract off the manifold. You get faster more accurate air temps that way. In manifold style the old maf cars had sucks

 

Agree, but don't forget to calibrate your MAT table into an IAT table.. Threads exist.

The intake isn't tapped for any vac fittings, something to consider before bolting it on.

-- Joe

 

You would need to run a spacer that has fittings for vacuum or run an intake elbow with ls1 type tb and use fittings on there.

Or use one of the 3/8 or 1/2 npt fittings and put a large vacuum line off that and put reducers/tee's and taps off that for your vacuum source.

 

when you order a ProRam by Accel Now, you get the motown intake in a accel Box..
with fuel rails, it's just under $489 now.

out of the Box it Fits and bolts upto the AFR 220 Elmtr Heads using the felpro 1206 Gaskets. it has 1. 1/2 npt Fitting, in the back,just under the TB.

and room on ea side to install 2 more if needed.

i posted pics to show..no clean up needed. bolt on and run. all made in USA Parts. that fit!

 

I can drill & tap in the back of the intake for a MAT no problem. And my Eddy TB has plenty of vacuum ports on it. I don't even run power brakes anyway. haha

 

thank for the Good Deal on the TB. woody.
ill be sure to leav your First Feed back, for you.(Classifieds Rating)

have to do it from the forsale/looking for part (url)

Jeff

 

Happy to sell it! As you can see from my engine bay pic I don't like shiny stuff. haha And the Edelbrock one is a little shorter with the linkage a little closer to the carb pad to clear the rails beautifully.
