Just picked car up from tuner, I put ms4 with 111 lobe sep. and th350 with 4500 stall. WOW big differnce it pulls like hell. I thought it would have more of a chop but as long as it runs good thats all that really matters.

never seen it disappoint. put it on a dyno? when are you shifting it?

No its never been on the dyno. I shift it at 6800. It just keeps pulling and the circle d 4500 converter puts it right in its powerband. Its still pulling hard at 6800 im just scared to take it over 6800 with stock rod bolts.

Do you guys think im pushing the stock rod bolts shifting at 6800

What can I safely rev the stock bottom end to. It's 1999 LS1

That is really pusing it far with the 99 stock rod bolts.I would keep it to 6500. On mid year 2000 models and newer, they have stronger bolts and we are shifting them at 7000-7200. Get the Katech replacments and follow the instructions.

^good info , i love the ms4, pulls great, you going to change gears, i have a 6 speed but 4.30 range works great with that cam

Guess im going to be ordering some rod bolts. I probally keep the 373 due to i have plans of putting a 150 shot. What rpms guys trapping with 430 gears?
