Default MS4 Big Difference

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.

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.

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.
