Hey guys, above is a link of a Edelbrock top end kit I am wondering if would help out on my car and if its worth purchasing.

I have a 1991 Camaro RS with a rebuilt TBI 350. If I were to do that kit... I would also be getting the Holley TBI upgrade which I believe is 670 cfm. I would also get the Holley adapter plate to fit the carb intake. I plan on leaving the bottom end untouched with an exception of timing chain and of course the cam. I have a new MSD distributer for the car already and the rear gears are a 342 posi I believe.

I had a blown headgasket and ripped it down and no way will be putting all the stock crap back on. Please let me know what you all think or if you have any better ideas.

I am really wondering if that cam would be too much for TBI?

Also, when I do this I will have to get my chip tunned, does anyoneknow of a good place to do this?

Thanks.

From what I know. That cam size will be a major pain in the **** to tune. And I have also read that you do not want to runner a RPM air gap with TBI. because something about fuel puddling up and also being a major pain to tune. I am sure someone with more knowledge will come chime in

Ya, I really have no idea what a good combo would be... thats why I was looking at that. But yes, I did realize the cam was pretty big, and thought it would probably mess with my power brakes an all too.

If anyone knows of a good combo to put together please let me know.

What would be a good head choice as well.

I am not looking for crazy power... over all over time I want like 400 or so. Nothing major. I just want her to run and not just be all looks.

180cc AFRs if you want an aluminum head. IMO.

... and don't forget the FAST EZ EFI retro kit. solves your tuning problem!

that works with the stock throttle body?

thomas1976

I would use a dyno simulator http://www.summitracing.com/search/?...no%20sim&dds=1 and run 180-210cfm cnc AFR, TFS and similar heads, with cams around .500 in lift 220 duration 112-114 LSA.

This will give you a good guideline.

Tuning would be plug and play with EBL flash http://dynamicefi.com/

Ok, I am finding a lot of cams on summit within the range you had recommended. I was wondering, will these specs give the car a nice mean lope? The other thing I am seeing, this one I dont know the answer too and did a search and still havent found an answer, but, I see they have computer controlled camshafts as well. Would I have to get that becuase the car is computer controlled, or does that not effect my camshaft?

thomas1976

Yes computer = computer friendly cam is required.
With camquest6 you can chose lopy idle sounding cam's.
If you are good at tuning you could try a 110 LSA.

Ya, I don't have any idea on the tunning aspect, I figured Iw ould have to take it somewhere to get that all figured out. Thanks for the posts. I will keep looking for a cam, then I guess go from there. I see Comp cams has quite a few computer controlled cams....

UnderCover89TBI

Yeah ive been looking into comp's cam's for computer controlled too. I am going back to roller with my next setup I ditched it when I rebuilt my engine.

Ya, the seem to have the best selection.

I was also wondering. My car shold have a flat tappet am I right? I guess I will find out once I pull the cam and look at the lobes.

UnderCover89TBI

iTrader: (25)

well the stock L03's have a hydraulic roller cam stock. now I changed mine (I am an idiot) to a flat tappet style. So your motor is a 350 so I am not entirely sure what it would have. If it is a truck engine from 87-95 it will be a flat tappet. If its older than that it'd be a flat tappet. what did the engine come out of?

thomas1976

Before you pull the cam, the intake manifold has to come off and you will already know.
Some later 350's that came with flat tapped are machined for roller, just need spider, dogbones, roller lifters and retainig plate for a roller upgrade.

XxGeinNothingxX

Ya, I was told to believe the motor was from a 1991 caprice police car.

How do I tell by pulling the intake off. Do you look at the lifters?

Ronny

E Tec heads are very very good.
Cam choice is doable but maybe not for a beginner tuner.
Intake being air gap might work for a hot climate but terrible when temps are <60dF. Intake would need to be heat soaked to function regardless of intake choice.
I would use a single plane weiand low profile with a adapter plate and a 7.4L GM TBI with 75-80 lb injectors and VAFPR with TPI pump. Add a WB sensor/controller.

Second thought I personally would do none of above cept cam and heads choice and run port fueling with EBL-ECU. For what you are investing "port fuel" is way to go.

Flat tapped https://www.thirdgen.org/forums/post...705-post7.html

Caprice LO5 have roller cam.

Ya, I knew once I pulled the lifters and cam. Got retaining plates, roller lifters, cam lock, all that good stuff. So I do now now its a roller.

I am looking for a cam now. I found one that would be close to what people have recommended.

It is a 210 duration, little under .500 lift, and 114 LSA. Would that still sound good and a bit lopey, or will it be really mild sounding?

XxGeinNothingxX

iTrader: (1)

I did the Comp Camquest 6 app and one of the cams that came up were close to the recommendation on here except for the lift.

COMP Cams 12-466-8

The cam is a 218 duration, .570intake, .565exh., with 113 duration.

What should really be my aim for lift?

Would this cam work for me as well?

thomas1976

Supposing CNC TFS 195 and /or similar, what comes out comparing that 8-466-8 to something like 8-502-8 or 8-503-8 ?

With the right intake this could be someting around a 400rwhp build.

I would aim for the lowest lift and greatest hp.

Ronny

iTrader: (1)

MILD. I ran a 210/214 for 2 seasons. I will say noticible that a cam swap was done by trained ear. Thats about it. Look at CC chart and go up one.

My current cam is 224/230 114 LSA. and is a bit too much for my 3.07 gears/manual.

XxGeinNothingxX

iTrader: (1)

I thought it may be mild.

I do believe I found a couple things.

The cam I am looking at getting I think is a Comp cam 8-302-8

210/220 duration, .480/.480 left, and 112 LSA

I think it would be a better sound as well.

The heads I was looking at and please let me know if these would work well...

Trick Flow TFS30300001

The have a 56cc Cumbustion Chamber, 175cc intake, and a 67cc exhuast. I will be honest, I am not sure what good numbers are for these, I see these are pretty low comparred to other heads, and the lift on these matchs the cam lift.

If these would be a good match, I am on to checking out intakes and also wondering if I would need a dif. size pushrods than I already have.

I appreciate everyones input on this so for.

thomas1976

Any particular reson for choosing that 305 head?

If your engine is alredy built post all # you need to fill out http://www.kb-silvolite.com/calc.php?action=comp this will help find the desired combustion chamber cc, for a decent CR.

Sorry, but this build is not going to be 400 RWHP - that would be close to 500 flywheel horsepower. To get 500 HP out of a 350 requires a thoughtful build from scratch. Additionally, it is not easy to build a streetable 350 that makes close to 500 flywheel HP - you need high flow heads and a radical cam, something in the 230-240 degree duration range. And you are wanting to use TBI for induction.

I'm not beating on you, but just saying don't spend a bunch of money expecting that power level and then be disappointed you didn't get it. 300-350 RWHP is a much more realistic goal (350-400 flywheel HP) and I think the comments here are on track for something in that range.

thomas1976

Yes true, around 350rwhp seems more realistic with 11:1 CR, CNC TFS 195, 8-503-8 and matching intake. Using desktop dyno5.
