Hey guys i have a few questions for you guys. First of all, I'm not the most knowledgeable person about Chevy 350's, I'd just like to pick some of your brains about this, because I know the knowledge on this site is unbelievable.

First of all the 350 I have is bored .040 over, the previous owner said it was 11:1 compression and 4bolt main. It has a comp-cams .507/.507 lift 292/292 duration. Comp-cams #12-213-3. The heads don't look like anything special, I haven't pulled the valve covers.
It has a Demon 630cfm 4 barrel street demon carb and roller rockers.

I haven't really reved this motor up, only to about 4,000rpm. It seems to be making alot of power. The previous owner said it was 400hp, although I don't know, the car really seems pull great once you rev to 3,000ish.

1)How high can I safely rev this engine and it stay together? 5500-6000ish?? Whats the safe-zone usually on an uknown engine. Or can you guys give me an approximate redline from these specs???


2) Lastly, the car has 3.73 gears and a muncie m21 tranny, hooker super comps and a world products dual plane intake. What do you think this car would do in a 1/4 mile, roughly

lastly, engine is relatively new built around 2001 with around 1,000 miles on it

 

Not knowing exactly how it was built makes it a tough call. Most likely, it is not making much power past 6000 anyway so I would keep it in that range to be safe.

 

13-14 sec 1/4mi???? Thats sounds like a safe bet. I wouldn't know for sure, but thats what I would guess.

 

What intake manifold are you using?
