hey you hear alot about lingenfelter and their 427 engine but doug rippie has a 427 and make much more power. does anybody have this DRM 427??? and why so much more power??
I thought the only 427 Lingenfelter was the twin turbo making 725 HP? Anyway, the DRM looks pretty nice. But you can get close to the DRM Hp with a Magnacharger.

No doubt that Rippie and crew do great work but $26,000+ for a 427 stroker is pretty steep. My MTI 422 stroker is less than half of that price and Agostino is very close to the MTI price (neither include the aluminum radiator and cooler though).
Anyway, it's all good
they do say that they usually get 11.7-11.9, but i dont think its worth it for 26 grand. but then, thats just me
<edit> OOOHHHH heres a more interesting quote:
It is extremely important to note that this car is NOT a drag racer. Although it does extremely well as one, that is not its purpose in life. This is a lay me down, balls to the wall ROAD RACER that you can race on the weekends and drive to work everyday of the week, rain or shine, -20º to 110º F, highway or city driving. That's a tall order for any tuner and we have accomplished that with flying colors! By the way, C&D managed 19mpg city driving, not bad for a 500hp emissions legal catalyst equipped "race car for the street"!
i think that better summarizes this package...

DRM's 427 starts with a C5R block. It is not a stroker and is a much better platform than a stroker. Much of the cost is based on that block. Also, the last several 427s they built dynoed at about 600 hp at the crank in a mild cam road course set up.
DRM buys some parts from TPiS, but I would not say most by any means. Much of what they do is race tested going back to when they fielded one of the most successful World Challenge race teams in the 80s and 90s.
Lingenfelter wins the Supercar Challenge in 2002 put on by Car and Driver. I don't remember a DRM being there or anywhere.
Lingenfelter has be doing this for Years and Years. My money says Johns the Best.
Ask Zdog.

Couple of questions...
Is the C5R block that much better than the LS6 block? If so, in what way?
Why is it a better platform than the 422 stroker?
In your opinion, is the this setup worth the additional $14,000 over the 422 stroker (and why)?
(Just trying to continue my education here)
Thanks, Rippied
I'm no engine expert, but that block is trick from what I understand. Much stronger than an LS6 block in ways I don't fully comprehend. I guess that's why the C5R race team uses it and not a stroker. I'm sure one of the mechanical gurus on the Forum will help.
A friend of mine has one of Lingenfelter's 427s and it is sweet. No doubt about that. Makes about 460 rwhp which is probably not as much as newer Lingenfelter 427s. It was a very early version. It has been trouble free for 20,000+ miles.

For 26K why not just buy a true blue C5R engine... the Lemans winner right from Katech...
I also remember Ktech selling the 7.0L short block... but I don't remember the price and they don't have it on their site anymore but it was a chevy part.

OK, one of you engine gurus....get over here and edukate me
My questions are in the above post....

One of the strengths of the 7.0L block I've heard listed over a stroked and bored engine is that it has thicker castings, where as the bored one now has very thin ones (as they have been honed out).
I'm sure with the extra aluminum they make other things a little stronger as well (more tortionally rigid).
hey mikes this is what i found: What is neat about this block is that the cylinder sleeves are removable, the main bearing caps are billet steel, the block is made from a much higher quality Aluminum than the stock C5 blocks and the cylinder heads are mounted using studs instead of bolts for added strength. Designed by GM to have a 4.120" bore from the start, with a maximum of 4.130". Since it is meant for racing, it's a beefier, stronger, and more expensive block than the stock unit.

Seth, thanks for the feedback but since the sleeves on the stroker are pretty thick, wouldn't this offset any 'thinning' of the cylinder walls?
