HELP! L98/superram/vortec TPI intake? - Third Generation F-Body Message Boards

nelson84 · 01-31-2008, 12:20 AM

I have the above mentioned parts. I would like to install them on my 85 vette. Which vortec heads to get to fit on my engine? The stock heads are the iron heads, now will the center bolt vortec heads bolt onto my engine? Should I get the lingenfelter 219 cam for the superram?

Or should I sell the superram and just get some large tube runners for this project to avoid the hassle of grinding the runner to make it fit on the TPI vortec intake?

I think you should sell the Superram, to me. PM me if you want to try to work something out.

Nelson,

Welcome to the board. What rear end gears do you have? I ask the because on my first build I ran a tpi with twisted wedge heads and a mild cam with 3.27 gears. This gearing was perfect for power on the street while achieving 70mph at 2200 rpm. Now that I have switched to a super ram and that 219cam it seems as though my 3.27 are simply not enough. This type of setup cry s out for at least a 3.45 if not a 3.73 or maybe even 4.10 which is like a declining scale as it relates to gas mileage-freeway driveability.

So the real question here is what is your aim for this vehicle. Is it a daily driver, weekend warrior, or is it trailered to the strip? What do you want from it in terms of a power band? What is your budget??

So you have a super ram and the vortec base and you wont heads to make this all work on an 85 vett, if i read this right. Well your changing heads so just get the regular vortec heads with the vortec pattern and that will match the intake baseplate of the vortec. the other difference is the self align rockers you'll need thats all, other then gaskets and bolts ect...

Its an 85 vette with 3.07 gears auto. Would the 219 cam be best or go with the 211, if I keep the superram. So I just have to get:
gaskets
vortec heads
rollor rockers
roller lifter
new rods
and a cam 219 or 211?

i just built my 91 camaro's 305 tpi motor

put on the edelbrock vortec tpi intake, summit racing vortec heads, comp cam 212/218, flat top pistons, hooker 2055's, taylor wires, accel spark plugs, etc

only driven it 3 or so miles .. ran into a slight spark plug problem with the e3's i had (DO NOT BUY THEM) .. but last time i drove it , it pulled really nice .. a good bit more than stock ..

but i just figured out that one of my injectors was unplugged .. so i have been missing a 1/8 th of my power .. lol

if you want a daily driver w/ good mileage and GOOD low end torque .. and you dont plan on out revving a 4 cylinder .. than use the vortec tpi setup ..

if you want a drag car w/ high rpm capabilities .. use the superram

Personally, I'd lean towards using the 219 cam. After all, it was designed specifcally for the Super Ram intake. You'd probably be leaving a lot of power on the table using the 211 cam. With the Vortec heads and the Super Ram, you should have a nice, stout, street motor. I agree that the 3.07 gears will probably be a detriment to your setup, but it makes more sense to me to use the right cam, and then gear up accordingly. 3.55's or 3.73's would probably put you in your power range a lot quicker. I'd also recommend getting a stall converter in the 2400-2800 range.

if i could build my camaro motor again .. i'd go for a high revving v8 w/ the superram ..

just b/c it sounds awsome when a v8 rev's up more than a stock civic ..

just got mine all working again and adjusted the timing and fuel pressure .. mine has a boat load of torque starting around 2000 rpm .. i mean it PULLS ..

and i havent even tuned mine yet .. im running the stock chip /ecm

just depends what kind of car u want it for .. if i was using the superram you'd want to get a cam to match the powerband capabilities .. whereas tpi has its limits

and its like the honda s2000 .. when are you going to use the 9000 rpm in city traffic, all your power is up in the higher rpm's ..

you get what im sayin .. i wanted mine as a daily driver / kinda good on gas .. so i went with the tpi so i got the bottom / mid range torque .. but if i wanted a "every now and then driver" / drag car .. then i would go with the superram

I've also got a Super Ram intake that's going on a fresh 355 motor with AFR 190 heads. I going to try the Comp 502 cam with mine (218/224 @.050, .495/.502 lift, 112 LSA). I'm hoping that cam will be a good compromise between low end/top end for a street motor. I almost went with the 503 cam, but I'm hoping the 502 will be a bit better for the street. I went with the Super Ram because it'll handle some pretty large cams, but it still has decent low end torque as well. I'll get the chance to put all this theory to the test when the weather warms up enough to put the new motor in.

Adrians91Z28 · 02-04-2008, 12:09 PM

i got the 501 cam in my 305 tpi ... and ive done vortec heads, edelbrock intake, hooker headers ..

and it runs fine with the stock tune (probably could get some more power with a tune) .. but it has decent street manners .. and if you had a 355 .. i would think the 502 cam would be a nice choice .. and you should still have a good bottom end ...

right now .. mine has a little power under 2000 rpm .. but once you hit the powerband at 2 grand .. it kicks you in the seat and just keeps pullin ..

i havent looked at the specs of the 503 .. but im wondering if that might be a better choice since you got the superram .. guess someone else could chime in on that thought ...

but my 305 with the 501 is a very tame motor .. slightly noticible idle with the stock tune .. and exhaust sounds awsome with a flowmaster / stock pipes (soon going to 3" mandrel bent) .. oh .. and i removed the cat b/c of my 3" y pipe ..

Pat Hall · 02-05-2008, 03:13 AM

I hear ya Adrian. I've really been straddling the fence over using the 502 or 503. Actually, the specs are so close between the two that I'm probably just splitting hairs, or over-thinking it! Spending the money isn't a problem since I've already got both cams. Oh well, I've got a couple of months to make up my mind since I'm waiting for warmer weather to put the new motor in anyways.

If the 501 cam is really as mild as you say in a 305 motor, maybe I really ought to use the 503 instead.

Adrians91Z28 · 02-05-2008, 12:21 PM

actually .. since you got a 355 AND the superram .. i'd go with the 503 since you can flow the air .. plus more air + fuel = more power

and when you tune it .. it should still be a fairly tame street car .. with a real kick in the a$$ when you get on it ..

Run the 219 cam it will run great!. My 1986 vette with 3.07 gears and the engine that is in my sig ran 11.81 at 114MPH. In my slightly heavier harder to launch firebird it runs low 12's. The 3.07 gears and 2700 RPM stall will work great.
