Let's assume...bench racing a claimer motor.

This is easy 6.3l LS motor with the L98 heads, send them out and have them ported by whoever your favorite porter is, swap the cam, angle mill the heads to bump the compression and you'll easily make 700hp........

that's what I am thinking as well. But, we'd probably be aiming more for 600hp and a higher average HP. One thing Engine Masters Challenge will teach you: it's VERY easy to achieve higher-than-stock PEAK power. It's harder than hell to achieve AVERAGE power that's higher than the stock powerplant. No shit!

but this is similar to what my favorite head porter suggested.

I wonder how a set of Cathedral Port heads like the LS1/6's have would do for power down low, I'm thinking they would have better low lift flow numbers than the L92's........... Might be a better match if your limited to 6500rpm.......

[Bob Holmes]

Any Mopar action here? How about a small cube big block?

[Barry Donovan]

Because the winner is the guy who makes the most average power and torque from 2500-6500rpm, *per cubic inch* - big blocks get their asses handed to them at this game.

Bob's talking about the proposed new class for Engine Masters Challenge - a $4000ish claimer class. A 6.0 LS (need the big bore to minimize shrouding) with a mishmash of OEM parts, the proper head porting, intake and exhaust design, and cam selection should kick ass in this contest.

I wish they'd require the carburetor and EFI system be a part of the $4000 claim however. But too many whiney carb guys who run their mega-buck, thousands-of-pulls-to-tune Shop Carburetors would cry about having to let their priceless gems go for $4000...

I'd gladly let my $180 megasquirt go with a claim. I also think EFI guys would have the inherent advantage here - EFI pretty much always out-torques and out-averages a carburetor.

that is the most twisted backwards read I have ever let sink in.
and you forgot suffixed zero for the megasquirt moron.


I agree with stich. make some money if 4000 is the limit by using cheap tried and true, and ignore youth with their megasquirters squirting all over everybody..

(in the infamous ButtHead voice) Wooo.... he just call you a moron...........That was cool........



Just play'n buddy.........

[Bob Holmes]

Let me be very clear, I have no idea what rules they have settled on. They aren't announced until PRI in December.

I just have a certain philosophy...

As SBG observed "You're not cheap, you're value priced?"

don't even think about starting shit with me Shakespeare. You're the guy here who idolizes carbureted subaru engines. Let's not forget that.

[38P]

Assume pump gas. You assume correct.

I would go CHI headed Ford except for the claimer limit.

Yeah, that would be too expensive. As would be a lot of these ported GM combos bandied about, unless the parts or the porting's almost free.

The ratio of cubes to average airflow for a ported Mark VIII looks pretty good (if it's legal). Low-lift flow would be dynomite. But a suitable intake is still a problem.

Dulcich would probably like it if somebody showed up with a 383 B MoPar. But the budget's kind of low for that unless you've already got the core and some parts lying around. The non-adjustible valvetrain on the Gen III Hemi might be an issue at this price level. Still there ought to be some used ones around that might make it attractive.

As SBG observed "You're not cheap, you're value priced?"

Ya and we all know a LS motor is the best bang for the buck........

[SpiderGearsMan]

RACERS USED TO USE BUICKS , AMCS , OLDS ...engines nobody wanted to claim

[TC]

It's a claimer motor, you use the parts the motor came with.....And I'm sure Bob know someone that will majorly hook him up on the port work........I know my machinist would do it for free for just being part of the team......The advertising alone is worth the work........So you spend the money on valvetrain and not worry about the rest.......

[Mater]

this is true at the local dirt track the current winner runs an olds 307 no one has ever even showed interesed in claiming it lol


i would think a 403 small block olds with stock big block heads would pump out a lot. just find a way to support the block form ripping in half fromt he windowed mains

How about a Pontiac 400 or 455.........

[Mater]

the 403 has the same stroke as the other small block olds engines 3.385" but a massive more 4.351" it also uses smaller main barrings so it will not put more stress ont he barrings being reved that high. if the block in girdeled you could probably get it to 7,000+ easy

the pont 400 and 455 would be sweet too but i like olds more lol
