This is a very strange issue because it only happens when I'm towing my trailer. It seems to run fine most of the time but at times it will loose power and some times act like it has a misfire.
In my 90 burb with stock 350 TBI motor.
I will let everybody how well or how bad mine works when I put the 454 in the burb.
The trans has already been built, how well I have no idea, and it already has 456 gears.
The 700r in my 90 burb works great. I tow regularly and the temp rarely gets up to 180 usually runs about 160 unless I am pulling a long hill.
I am getting ready to put a stock 454 in front of it. We will see how it does.
This is what I tow most of the time. It is small but it is old...
