this is for a 2wd mod. pulling truck.
currently is a stock crank and rod, 440 with fully ported 452 heads, team g intake and a dom 1050.
there are no cubic inch limit but this is going into a stock factory 440 block, with use of factory pickup tube. it makes 20-30 runs a year, 300 foot track. we norm freshen them every other year so i would say 50 runs on a motor. considering this is kinda last min and our season starts july 26th, on a short time frame. i would like to stay below 4,000 for rotateing ass. and heads or any other changes that would be over the current items in use.
