Car is a 1991 Camaros RS with a 305 TBI and a 5 speed.

Modifications planned:

Heddman Headers with the Y-pipe
Dynomax Cat
Dynomax Cat-Back
Fastchip from Fastchip.com
Edelbrock TBI intake
75-125 shot of nitrous

What kind of times should I expect?

Thanks!

Chris

 

with a 125 shot . I would expect mid to upper 13's just my .02.

 

hard to say with stock heads and cam. Those will both kill you. Plus the stock rear end and single snorkle air filter. Get an open element ($60 with k&n) and a 3.42 10-bolt ($325), lt1 cam ($40), and even some cheap 305 tpi heads ($150) to go with that combo and you'll see mid-low 13s with that 75 shot. I wouldnt have the ***** to squirt 125 though

 

Where do I get a $325 10 bolt 3.42 posi? Id like one

 

Mike-
Why not just go w/ the SLP posi unit $85 with Richmond Gears ($190) from Summit.

 

Yeah, I got the SLP take-off Posi for $84 and some 3.73s from ebay for $88. Not I need speedo gears ($25) and an installation kit ($60) and I gotta guy who's gonna install it all for $150!! That's not bad and I've heard I'll get .5 or .6 for it, I hope so

 

Check the classifieds here, camaroz28.com, ls1.com, etc. Any 10 bolt from a 3rd or 4th gen will work, or a 9 bolt borg warner.
