So you guys know we need to build a new engine for our drag car. Our latest motor is a 377 SBC, 13.7 Mahle, 6" Eagle rods, steel 3.48 crank, splayed 4 bolt, Brodix track 10 heads, Enderle bug catcher on alchohol. We lost a roller lifter and took out a valve, piston and holed a head, nothing that can't be fixed. But, since we are going to spend money on the Brodix heads again
I had thought of going with the SB2.2 heads instead on the 377. Then I thought might as well go for the inches and build 434 using our 400 block with block filler for stability. The feedback I get is that it is a waste to build a 434 without a good aftermarket block as the 400 walls would get to thin going out to 4.170+ although our 377 has 4.155 now. Then there is also the possiblity of using our spare 400 .30 block and building a 406 with the SB2.2 heads. Still might since we have most of the pieces.
BUT...
Since it is a Mustang I toyed with the idea of building a Ford motor.
A guy I work with has a 70 351 4v Cleveland motor that he will give me if I get it out of his way. I read a couple of engine master articles on the Cleavors and It sounds like those heads can be made to flow pretty well. probably on the order of the Brodix- upper 280+, definitley not like the 380+of the SB2's.
The draw back is that I don't know much about Fords and I don't have any ford parts. So maybe that is not such a good idea after all.
What do you guys think?
Here's some parameters:
Stay with a SBC , want to run 9:90's all day long, but still stroke an occasional 9:00 just to know that we could, no nitrous- been there done that, stay with the bugcatcher but either gas or alchohol.
What do you think?
