i bought that bankruptcy car that came up a while back. since we're on the jbl site i'll post a helpful tip.
both cars had cooling system issues because of the way they were put together. make sure your catch can is connected at the bottom to the overflow hose and vented. the rad cap is going on the pressure side, so you have to take that into account for cap psi. the pressure side will develop close to 15 psi because of pump flow pressure so you have to account for temperature rise on top of this. i now run 22-25 psi caps on both and have no problems which is recommended by howe for their radiators. by the way, i had to purchase a rad for the goins car and howe said the rad was good for about 400 hp, so make sure the rest of your cooling system is adequate. the rad in the goins car had the cooling tubes blown out like a football. the lit that came with the new radiator said if the coolant is run low and coolant comes in contact with a hot cylinder steam is produced which runs through the system and the radiator can't handle the pressure, which causes the cooling tubes to blow out. with the crate motor i have a 160 deg high flow thermostat and it will hold 180 temp at idle, i replaced the water pump reduction pulley with normal size also, i would not run a water pump reduction pulley in these cars. the race car has a 180 but i think i am going to have to drop that.
the rear diff has to be mounted solid. the goins car had a rubber mount on the rear mount of the diff and had tore loose. we couldn't figure out what the banging was in the rear and raised the car and put it in gear and the diff was flopping around, the only thing holding it in the car was the two front mounts. it was kinda exciting to watch that thing jump around, i couldn't get the guy in the drivers seat to shut it down quick enough.
john, if you get a chance could you measure the thickness of your front and rear bushings for the diff? i need to make some proper mounts and have the correct thickness.
oh, keep those pics coming!
since the cat is out of the bag i'll post this pic. enjoy.
