So speculating that Dart's LTx block may come with a 4.125 bore, what cylinder heads would be appropriate? Looking for big cube combo's. Providing that you would be able to sqeeze a 4" stroke in this block. I'm guestimating that a streetable 427ci could squeeze out a respectable 550 rwhp. Naturally Aspirated of course. Do you think the LTx intake will be too restrictive?

Thoughts? Expertise?

 

brodix will cast you whatever head you want for a LT1 for an extra $400. You have to order them through a dealer they do not sell direct

 

I'm a little out of the loop lately so what dealers sell Brodix heads? I'm sure with those heads we're talking custom intake.

 

they can do a LT1 bolt pattern or a regular sbc intake, Its nothing exotic

 

DART Pro-1's. I'm using the 215's on my 414. They also have a 230 cc head. Their price for doing the CNC on the pockets is very reasonable.
