i've added a few things: AS&M runners( ive ported the stock base and pinlum to match) and a crane Z cam (218/230 .459/.486 112LSA). ill admite that its big for a stock headed TPI but it sounds GREAT. tell me what you guys think.
btw it has a stock chip in it that will be replaced with a custum one.

here's a pic

 

sounds really good!!

 

Sounds good!!!!

Your stock heads are killing your power potential.

 

DId you use a older block with the tpi on it or you put a flat tappet in place of a roller?i have a 447" flat tappet and it has a slight lobe to it and i want to upgrade and the guy that did my motor said he has a 480"lift cam that would work great .What exhaust do you have?

 

thanks for the compliments.

it actually has a stock exhaust with headers and no cat. a cat-back will be one of the next mods. the stock head are going to find there way out when i can afford some 180 AFRs and maybe a 383 stroker kit. ill probably get the base extrude honed. it is a factory flat tappet motor. 85L98.
hey nighthawk how much hp sould i be pulling with this?

 

sounds killer, thats the excat idle I want, what is you idle rpm?

 

That's the idle I want too,what's the part # on that Crane Cam you used?

 

Wow that sounds really good for a stock exhaust!!!!!
Im not trying to be an *** but there is no such thing as a stock L98 in 85 you might want to do some research on what motor you really have because if it is a 350 then its not the stock motor and if its the "stock" motor then it is a 305.

 

it is... it came out of a 85 corvette. it might not be an L98, but it is a 350. i check it when we put it in.
here's the cam http://store.summitracing.com/partde...2&autoview=sku
the idle is with the stock chip. it idles around 700 rpms, but it surges a little when its cold. it needs a new choke.

Thanks alot,that idle sounds awesome,I even saved that clip to my email.

 

if you have a SD tpi then it wont idle at all with the stock chip. i have the MAF. and thats a flat tepped cam.

 

I've got the maf,so I should be good.

 

FWIW, My 85 Vette is a factory stock 350, aka L98

Your's sounds nice!

 

holy cow stock exhaust ??? Sounds like a borla !

 

i talked to my dad, and he said he did put a flow master muffler in it but he dosent remember what kind of flowmaster it was

any who ill be getting a cat-back soon!! what kind do you guys think i should get? are if i should just leave it alone?

 

I kinda like it as is.

 

As good as it sounds,I'd leave it alone,like I said,I saved it to my emal and listen to it all the time.Can't wait to have mine sounding like that.

 

I meant there was never a l98 or any type of 350 in a 85 f-body,sorry

 

agreed you could run a 3" pipe from the y back though

 

it does. i found that out when it got the Y-pipe made for it.

its all good ws6gta89, but you are right, there were none for the Fbody. i just pulled the old switcharoo when the 305 spun a rod.

 

Looks good man! Sounds really nice to boot. I had better get to finishing my car up to stem the tide of jealousy I'm feeling right now

It's nice to see that the runners really do look stock. Here in CA my car gets the smogging equivalent of a night in prison as "the pretty guy", so the more stock-appearing the better.

Post up when it's tuned. Nice work!

That sounds killer!!!! If it was mine I consider leaving it like that. If you add a cat back the tone may change alittle.

It does sound alot like a Borla, mayh be you should think about getting a Borla cat back, might keep the same tone.

That sound is making me consider keeping my ZZ9 cam I got.

 

Dayum. Sounds good.
I wonder how mine'll sound with full lenth headers, true dual 3" and my cam that's 224/230 .566/.570 112lsa.
