Exactly, so why would u want to use a convertor that is slipping more than it should? Its all about combination and That combo would be better off with either more gear or tightening up the convertor and since he drives it as much as he does it would make more sense then to tighten it up.
Your car mike just giving my input.

Hey guys, I appreciate all the thoughts and input. I love talking our cars, and you have some sweet combos.

And you guys are also right, I may pull the converter and have it tightened up some day. I just got it last summer and just got it running in the car last July. But my combo wasnt as strong last year and the 10" conti was built for that combo. I am sure now, it would be done a little different if I have it redone.

So that could certainly happen, just not in a hurry to yank it out and send it our during the season.

On the interstate I normally cruise around 75 mph and it is around 3000 rpm.

Will keep you guys updated and also see you guys at Norwalk!

I'm running a similiar combo also,I'm approaching the roll bar rule with 3.42 gears and a 3200 Continental,I could go quicker with more gear, more convertor,slightly more compression,more cam,traction aids but I'm right where I want to be now.11.6/11.7 at mid 116's with a little tuning left to go.

Correct, but you are only using the 3200, compared to mike's 4000 + convertor, that is the only point I am trying to make here, and why his mph was down for having a engine that dynoed 550 hp! I understand everyone is happy with their combo's I am too

Darby, I hope you make Norwalk some year, it is just amazing for any fan of Pontiacs.

Formula, it is the cheapest holley regulator, so it could possibly be a restriction as well. I tried the bigger robbmc regulator, but blew the diaphragm twice. Last time was at the track, so we swapped this in. Haven't updated it since.

As for cruising at 75, that was with my old 3.23 gear. Last year the new converted and gear went in at the same time after I blew the rear. In hindsight, if I had to do over again, I would have stayed with the 3.23 gear. I now only cruise at 70 at 3000 rpm.

Here are some short videos from today.

Car cruising at 35 mph at 1620 rpm.

I do admit it is odd to run 11.43 and never hit 115.
But all my combos have always ran better ET than mph... Guess I am getting used to it, although I do keep making changes.

Maybe one day it will balance out

Although aren't they calculators that say what a car should run?
I assume I am close to proper ET for 550 hp, 3800 lbs, 3.42 gear.
Maybe not mph, but close in ET?
