Great project you have there, I almost bought a partially finished 34 Pontiac coupe street rod project years ago, but in Pa. you had to have full fenders on your cars and someone had discarded the originals and I couldn't find another set so I passed on it........ |

I believe the price is about $3000 but it comes with no fenders. Rocky

Is there an advantage to painting the inside of a block?

Promotes oil drainback and if there is any sand in the cast iron it seals it and keeps it there.

OK, so it's been a long time since this thread was visited and not a lot has happened but I have got the water elbows to fit the fronts of the late [1974 GTO #96] heads. It took a pair of 1/4 inch thick steel spacer/adapters. I had to "angle grind" the insides of the spacers with a burr on a die grinder [where the water goes] to align the coolant holes in the elbows with the coolant holes in the fronts of the heads. This works out great because the elbows were a 1/4 inch from lining up with the water nipples cast into the '59 front cover. [see post #71 of this thread with the photo of the mis-match] The 1/4 inch spacers help to align the parts as if all the parts were made for each other.
Now........I've been thinking about the problem of the coolant coming from the radiator into the fronts of the heads and curving right back around into the thermostat housing and back into the radiator without cooling anything and I believe I have a solution for this problem. Why not sandwich some shim stock between the coolant passage in the cylinder heads and the intake to block off this flow BUT! Don't completely block it off. Drill a 3/8ths hole in the shim[s]..[one on each side] to let a little coolant flow to the thermostat as a by-pass. Most of the coolant would be forced down the length of the cylinder head [except what little coolant goes through the 3/8th holes in the shims at the front of the heads] , down through the coolant passages through the deck and into the block, and back to the front of the block into the water pump. I see no reason why this won't work. I've got the 370 engine sat up on my little wheeled engine cart and have been running it 'till it gets warm........no cooling system at present. Got the cam "run in" now and I love the way this thing runs. The 230 degree cam [at 0.050 ] has a pleasant lope to it and even without the early Pontiac rocker stud oiling, the rockers get plenty of oil through the pushrods. Yet another fear alleviated. I'm sneaking up on it, fellas. By spring I hope to have the running gear bolted in the 34 chassis and testing it out on the road. Oh, and the quick change rear is out at the shop getting new axle tubes with ford wheel bearings, new 31 spline shafts and a vari-loc posi unit to replace the spool. .....and I scored a '67 Muncie 4 speed with the big counter shaft....it's a 2.20 low trans. I'll be able to adjust my gearing with the spur gears in the quick change rear to accommodate that 2.20 1st gear.

"and does not line up with the front water passages on the 1960 and newer block."
Yeah, I'm using a 1957 block and the coolant will take the same path is did in a stock '57 engine except I can't use water distribution tubes in the late cylinder heads. In my previous post regarding drilling holes in shims..........well, I completely over thought that statement! In fact, the thermostat will remain closed, blocking flow back to the radiator until heated coolant from the block opens it, allowing heated coolant into the radiator. The cooled coolant coming from the radiator into the fronts of the heads cannnot take a short cut back through the thermostat and into the top radiator hose because the cooled water will close the thermostat.........simple! My little brain fart. I don't need to make any shims, or drill any holes. Again the only changes from an original 1957 cooling system is the lack of water distribution tubes in the [late] heads. I should go back and delete all that gibberish.

Not sure about Jeff's coupe but we've ridden around in it at the HAMB drags. Ran a 10.98 after driving it to Joplin, Mo from S. Carolina. Pretty impressive!
I took this photo a year before he installed the blower.
