JP84Z430HP

Granny slips? That's my issue now! I really need to get to work on the tranny!

It WAS a decision between the headers and exhaust system or the tranny first, but even breathing through the LG4 manifolds and tiny pipes, this thing is too much for the tranny to handle!

I'd like to soo some comparison numbers on an identically prepared short-block with all the heads that have been mention here, including my expensive fastburns.

if i had the cash, or wanted to spend the time on the dyno, i'd be perfectly willing to put together a basic zz4 mtoor and start runnin numbers.... email car craft?

JP84Z430HP

That would be an idea! I think they've done something like that in the past (I haven't been keeping up very well!) but I don't think they have lately, and cylinder head technology for the Small Block Chevy has come a long way in the past few years!

I'm looking for an email address as soon as I finish typing this!

After all, dyno numbers vs. cost would be the answer to the topic of this thread!

Here's the thing

here's what would be ideal for them to do-

USE A ZZ4 short block!

those things are constanyl floating around, they are a cheap bottom end, and hold a pretty good amount of hp. Plus, the zz4 is pretty much the same motor as an L98 shortblock, same deck height blah blah blah.

just do all the heads with say 2 or 3 diff cams... use the same carb, same exhuast everytime etc.

maybe try a diff intake. However, i think the victor jr will be found to make the best power over 400 horse

i have the trickflow twisted wedge alum heads. i had it on a 9.2 to 1 comp ratio 383 motor with stock tpi ran 13.2 at 103.5 then switched to superram and got the mph to 106.i went thru a whole new motor rebuild with all forged internals. i just put the motor in the car but havent fired yet. still figuring out to do the dfi once its done i ll see how my newly ported and polished heads perform. i had the guy flow the heads before he ported to tell me how much more he gave me and he said that it flowed 251 cfms outta the box then ported them to 285cfms along with complete head work bowl and valve job and all the good stuff cant wait to see how my car runs.

So if I went with e-tec edelbrock heads, slp runners, accel base and ported plenum with the right cam and a fresh bottom end, then tossed a pro charger on all of that, could I see low 11's??? I have been wondering what to go with for months now, and living in Canada, it's hard to find company's that distribute afr and such!! My choice is either edelbrock or fully ported l98 heads. Any reply's are greatly appriciated here!!

91wtROH17's - The E-Tec's use the Vortec intake bolt pattern, so incsnay on the Accel intake.

The Jeg's heads are Canfield's. - CP lists the 200cc Canfield aluminums for $700 bare.
Pro Actions are $900 bare w/ CNC chambers($800 as cast) and make huge power. Every head shop I know of recommends them over anything else. A lot of top engine builders are also now using the Pro Action heads. - so, i just ordered my new 200cc's Wed.

later, justin...

I live like 1/2 hour south of Ottawa. I ordered a set of 200cc Pro Lighnings about 2 months ago. When they're all assembled, we should hook up and go for a ride and you can see if you like them or not. I can get you some decent deals at a place in Cornwall where I get all my stuff as well.

Thanks ****!! Cruz'n sound's great, keep in touch with that project .

AFR gets my vote for a 23 degree head.
Dart gets it for an 18 degree.

My old man has the Holley Systemax kit in his blazer. Its a 383 with 9.2:1 compression. He's pulling 464.4HP and 547lbs of torque. Food for thought.

has anyone had any problem with the fully assembled AFR heads. are the valves, springs, and retainers good. i am hearing that they are not that great but i don't have a huge budget.

The AFR's are top notch compared to other aftermarket heads, but they're not perfect. Upgrade to ARP studs, get tit. retainers if you want to spin past 6k, and get their spring upgrade or better yet a set Comp springs. Make sure to not get the regular AFR springs, which really are only good for about .525 lift although they say .550. I would not test these springs as others have had trouble w/ them. There's nothing wrong w/ their valves. AFR does a multi angle valve job on all the valves. My 190's and 210's had Ferrara exhaust valves, the 210's have Rev intake valves, and the 190's had Manly intake valves, I think, but don't quote me on that.

Hello everyone. Just found the board and signed up.

I no doubt agree that AFR stuff is great. I am surprised that more people don't think the same of Edelbrock heads. I've owned theirs, Darts, etc. and I was very impressed by the Edelbrock's and the Darts.

Here's a combo I ran, not in a 3rd gen camaro, but in a full size 67 Chevy truck:

406 with Edelbrock Victor Jr heads
70 CC chambers, flat top pistons,
A fairly big Comp Hydraulic Roller (248/254 @ .050)
Victor Jr. intake
830 Holley carb
1 3/4 headers with 3" dual exhaust
Powerglide trans
Big Shot NOS w/ 275 pills

Bear in mind all steel big truck with only a glass hood. How about 5.93 1/8 mile @ 114 mph. The heads were bone stock and the tune was very conservative. Same combo but with an Edelbrock nitrous kit that I got on a trade with the 175 pills ran 6.24 in the 1/8 with no tuning on the very first pass the motor made. I'd call those some pretty sporty heads.

I do admit that I knew pretty well where to put in the first try. I've been much faster than that in the past with prior combos.

I have another friend with Performer RPM heads that runs some very impressive numbers.

I completely agree that AFR's are great, but I think Edelbrock is the sleeper in the group and are very capable.

How about the Patriot Performance 23* heads. Patriot sells them for under $800 a pair for the non CNCed ones. You can get a bare set for under $500. I was hoping to find someone who has installed them on a TPI setup. I am hoping that they will yeild about 60 HP at the rear wheels with an LT4 cam or there abouts.

Check them out. People are selling them on Ebay too.

Hehehe another post bought back from the dead. Out of the box the AFR Elimators are now probably the best. If they are to be worked over than Trickflow, Dart, Canfield and a few others. Talk to your head porter.

I would love to see some Allpro 23* heads go head to head against AFR's new eliminators. LINK Their 220 std port heads are $1200 plus another $1200 if you want them fully CNC'd, which sounds like alot, but AFR says their eliminators are going up to about 2 grand, anyway. Ron's Porting Service looks like they CNC them as well and they have some pics....LINK


Looks like the pics on Rons Porting Service page are the Allpro 220 spread port version.

Yes their both about 2grand but the Allpro's are still bare at that point no valves, springs etc. The AFR's are complete but still the AllPro's outflow the AFR's all across the board according to eachothers product catalogs.

camarostylin

this may seem like a stupid question, but what's wrong with the valve springs that come on the AFRs to support a roller cam??
I'm interested in running some AFRs with a .564/.570 110 LSA roller cam.
