I have twin LT1 sbc's in my boat that dynoed out at 425. That's an option for you... I have Holley 750's with 1" carb spacers, edelbrock intakes, roller cams, and Imco headers/dry pipe exhaust. My weak point are my Alpha drives, but I don't want to get rid of them b/c I have Imco shorties on them... Regardless, be careful with the throttles and you'll have no problems. My boat has been rigged like this for 6 years now, with no problems. It's the fastest 272 LS on the lake, too!

I've heard that 312 rumor too, probably from the same people as you (Bald Knob sales), maybe Magicfloat would have some insite into this.

Put two of theese babys (SMALLBLOCKS) in a 292 and get a real beast

Do not mess with the stock motors...they are weak at best.
Build from scratch or buy new like above.

Price?? Or do I even want to know

Holy smokes. I think I've finally found something worth selling the vette for...1100 HP in my 292.

I will be calling these guys Monday for pricing. Anyone have a guess what a 6.2MPI @ 200 hours is worth?

$27,000+ turn-key... What the hey, you can't take it with you!! I'm hoping somebody with a 292 pulls the trigger.

See comments from Ray below. It is a sweet package! Would like to see several of them in use for some time to verify reliability though...
