Thread: 434 SBC info needed

Tweet

I wish you luck with the world and ohio junk. I went through 3 cranks trying to get a good 3.875 stroker crank from ohio. Finally just sent the 3rd one back and charged back my credit card. Got a Callies Compstar crank instead--- perfect out the box. Scat is also a decent crank for the price. As for the world block, it has serious quality problems. Do yourself a favor and google them. I'm not the only one that had problems with either of them.

As for the rest... 210cc heads will not come close to feeding a 434cid at 7K rpm. You need something in the 227cc range minimum. By the time you finish buying shaft rockers and such for the AFR 227's, you could get the Brodix Track 1 233cc heads ready to go, and IMO, a much better head for your 434cid. http://awesomeengines.biz/small-bloc...233-cnc-heads/ You might also want to consider the Brodix STD 18 degree head. It pretty easy to use since it uses all stock sbc hardware/rockers.

The Brodix heads come with 68cc chambers. You would need an 8cc dome (JE 182031), 0-deck height, .040" gasket, to get 13.9:1 compression.

I would do a custom cam. Comp doesn't have a part number cam that I like for this combo.
