onefaststang said:Brian, what type of machine work does the dart block need? I've been thinking that it's going to cost me about the same either way I go. The only reason I was considering modular is because of the strength of the block over the windsors block. I'm going to sell my heads to pay for new rods and pistons, so I will need new heads later on. I always wanted to go bigger anyways right.....
Rick, the cost of the Dart block is what was shying me away from the Windsor again. But then again, once you take a production block and put $1000 worth of machine work, etc.. into it your about halfway to the dart block, so I'm not sure what I am doing yet.
JR my plan is to get my car running with this stock 74 block then, start on a DART block motor, 4.125" or larger bore, 2.75" journal I know I am taking a chance but I could not swing the DART at this time just way to much going on (fully building the car, chassis 25.5 possibly, all new parts and getting married), I went in head first and I want to run next NMRA season. I know a lot of guys that have run stock blocks pushing the power I plan to make (800-1000+) and the key is the machine work and tolerances, some tricks, just need it to last till I can afford the better block.
From what I know about the DART, they need to be gone over and checked like any block for a high performance motor should be (align hone, hone lifter bores, final hone or bore, deck or atleast check for flatness) Brian had the best price I could find on a DART block
Good Luck with what ever you decide..
