I had a friend build the chassis, 2x3 1/4" tubing. the motor is a 355 sbc , iron double hump heads w/small valves 1.94. the motor came out of my 64 chevelle dirt track car that me and my buddy jody built in the 80's. ran it three years.when I decided to build a hotrod and got the body 31 sedan ,my buddy jody said he still had our old motor in storage and did I want it , well it's in the car as it came out of the other car 25 years ago except for the intake and carb, no rebuild ,yet, its got a custom grind john reed cam for a 3/8 th mile short dirt track, 2 bolt main w/1 rebuilt rod, turbo 350 4 link , 10 bolt 8.5 gm posi with a 4.56 gear, shortened with moser axles......I just pit the 4.56 in it and its laying over at 6400 rpm's , im going to have the heads checked, im either running out of cam or the 30 year old valve springs are a little tired. ill refresh it this winter and ive got a set of AFR 210 aluminum heads to put on it.....
