hell I reved my 228 232 to 7k every day ahhaa stock bottom end. Good luck

 

Bah, that cam's too small for a 5.3...

 

We just got the cam installed and there is a definite power gain! We haven't taken it to the track yet but it's definitely faster. It really pulls hard anywhere above 4000rpm. Suprisingly it feels just as streetable as the 221 and it feels like it didn't lose any bottom end either. We'll find out for sure once we get it to the track.

 

He just bought a Edelbrock ProFlo XT intake last week and it came in on ups today. We're gunna install it tonight and take it to the track this saturday so I'll get some numbers!

 

that sounds good... i've got mine set at 7500 rpms but mine doesn't kick in until 4000+ rpms...
i'm waiting on a 4000 stall converter to put on it...

how many miles is on your bottom end...

 

John cant wait to see what that little beast does..you should talk your bro into buyin that turbo kit

 

He's got 168k miles!

 

yea he needs it.. any how i figured id upload the pic you sent me

 

holy crap dude thats a bad *** intake manifold....

 

but with a 168K on the motor i wouldnt recommend 7k on the rpms unless your going to put some arps on it or some new bearings on the bottom end or something...
