Hey, i bought a rolled over trans am with a built up motor, currently working on putting it into my v6 camaro. I was just wondering if you guys could tell me about how much hp this setup should make.

1996 Lt1 79k on shortblock
3k on rest of parts
Edelbrock LT4 intake
58mm bbk throttlebody
Trickflow 195cc heads
Comp cam XFI 268 cam, 218/224 .570/.565
comp cams high energy lifters
roller rockers
comp cams beehive springs
msd cap and rotor
msd coil
msd 6al ignition box
pacesetter longtubes+ypipe, custom 3in to back
no emmissions, no cats
moroso cai, aluminum elbow
aftermarket maf
27lb new era injectors
wait4me tune
6 sp tranny
3.42 gears

Thanks!

 

VERY poorly setup car.
The Edelbrock intake has if anything shown to be a step backwards from stock.
The Trickflow heads are a poor choice for an NA stock shortblock due to substantial compression loss.
XFI cams are underperforming spring eaters.
Lifters are stock equivalant.
The MSD ignition pieces are at best unnecessary(cap and rotor are fine).
Aftermarket MAF only makes it harder to tune, no power to be had there.
27lbs injectors, really poor choice, that proves this is a WEAK turd of a setup, a good heads/cam setup usually needs closer to a 30lbs injector. I tried 28s on mine and maxxed them out enough to go lean.

Some 4.10s would be a MUCH better match to the 6-speed tranny, with the .50 overdrive even 4.10s are mellow on the highway. Put it this way, a nice mellow 2000rpm cruise would be 75mph.

Not what you wanted to hear, but the truth isn't always pretty.


The heads make a good foundation for porting for a stroker or for a boosted setup, but that huge chamber is the wrong way to go for an NA stock shortblock.

 

Pretty much true but maybe not the best way to express it. You should have done some more research before you bought all these parts. Test have shown the Edelbrock intakes make less HP than stock ones with the same mods. That cam is tiny and not a good choice, a custom cam would have been a better choice. What Cap said about the heads...100% true. With decent sized valves you won't be able to get decent compression on a stock shortblock. TFS heads do great on stroker motors but because of the longer stroke you are able to build more compression. Aftermarket MAF is almost never a good idea. There are lots of places to improve and unless you are interested in having tons of money invested in a car that really isn't that fast...I would reconsider alot of things.

Different heads.
Different cam.
AT LEAST 3.73 gears but 4.10's would be better.
A better set of injectors. Some good 30#'s minimum.
Stock MAF.

Again like cap said probably not what you were looking for but it's the truth. But if you did decide to put that setup together, I can't see it making but 350ish rwhp assuming you can get the tune dialed in.

 

He said he bought a junk car with these parts.

I am not a salesman, I just tell it like it is. Not my fault the American public has been brought up to believe they need to be coddled and sold on everything. World would be a better place if there was as much worry about facts and information as there is stroking everyone.

 

Well put.

 

ouch. this thread hurt and it's not even me, LOL

wait, you guys are saying that if i drop 4.10s in my rear i will be @2k RPM in 6th gear at 75mph?

that's what i do now at 80mph in 6th with stock gears

 

With a six speed and 4.10's, rpm in 6th gear is only going to increase by a few hundred rpm. right now I don't crack 2k rpm until i hit ~90mph.

 

what gears do you have? i think you told me one time i have 3.42's (stock 1993). what's the point of putting those in if the difference is marginal?

 

I think your car has 3.23 gears for a '93 M6. I have stock 3.42's (same as all '94-'02 M6 Fbody's). And it will only be a slight change in such a low gear. The differences in 1-4 w/ 4.10 gears is substantial.

 

What cam do you recommend in that general range then if not the XFI? I ask because I was thinking about that exact cam when I do mine, but it is going to be a relatively mild motor anyway...350hp maybe by the time all is said and done...mostly a daily driver that has some grunt.

* note...I also ask because the XFI is in the sticky which I did read and it says nothing about it being that bad aside from needing behives.

 

ah i see, but 6th seems to be relatively unchanged. I can't imagine how i'd have traction with bigger gears, i dont have anything in 1st gear right now, just all spinning. Maybe i need some nittos, these sumi's are pretty weak ;]

 

I'd look into running a cam like a CC503, or even better, Ai's 226/234 cam.

You think you have traction problems now, wait til you get your CC503 installed.

 

Yeah, no kidding. Do you think 275 nittos will hold me down with the cc503?

 

Street or track?

 

street.

 

They will do ok.
I'm about to drop a grand on suspension parts to make 1st gear a little more usable.

 

yeah, first gear is useless and im only bolton. i can't see bigger tires fitting on the wheels i have, seems like my only option would be to get some mickey DR's. those aren't cheap. not to mention i don't want to roll around town looking like i just got off the strip.

 

Gears play a huge role in performance, there is a vid in the multi media section of a

full bolton tuned LS1 with a gear M6

Vs

cammed LS1 with boltons and a mild cam with stock gears M6

The geared car would keep up with and pull a little on the cammed car

 

MT drag radials look just a lil more meaty than normal street tires........


Id send the heads out and have them do a mild port job and do a 383 budget stroker motor with a custom cam.

With the parts that you have now, buts thats just me

 

As nice as that sounds, i definitely don't have the budget for that at the moment. I'm pretty sure i'm going to stick to cam/bolton only, possibly gears. DR's are definately in order though, it never rains here... i have no excuse not to sport them
