Re: Video: Nascar Dodge R5/P7 Race Engine Lucas Oil Test

Of course the R5/P7 has nothing to do with production or "street" engines. And running the sort of cam timing, induction package, and compression necessary to make 800+ h.p. at 9,000 rpm with a two-valve pushrod 358 would not be remotely possible for a daily driver.

Sure, it's cool to watch, but it has almost no relevance to anyone outisde oval track racing. A turbocharged Gen III hemi could make a lot more power, get better mileage, and would be infinitely more streetable. And it would be something that would cost a fraction of an R5/P7 mill.

NASCAR racing has drifted so far from "stock cars" that it's almost meaningless.

Impractical, gas hog, stupid...I don't care! If Santa left that engine under my tree, the 318 would be out of the truck before lunch.

boy , do you miss the point
making that kind of power from a single 4 bbl 12:1 engine on gas is pretty good
those nascar boys can teach us a lot about airflow and efficency - that backyard turbo motor might make more power , but isn't going to live long
dang if those aren't SB2-2 heads - nascar is a joke

Make up your mind - they can teach us something, or they can't.

In many technical areas, yes. But they have huge money into CNC,
and R&D, etc.

Nascar or not, anytime an v8 engine does it's 'song', it's just plain cool.

Filmtip: when the camera is running in the dyno-cell and recording a run, turn-off the auto-focus function and manually focus on the engine first before hitting the record-button. This could prevent the image-blurring I think.

Re: Video: Nascar Dodge R5/P7 Race Engine Lucas Oil Test

I don't understand you guys. : They may be very similar to the Chevy heads, but Nascar won't let Dodge run the Hemi heads. And what are the chevy guys running in top fuel again?? A HEMI!
I would love to have one of these engines in my 4 speed duster. They are getting cheaper too.
And who said anything about these being for a street car? Maybe a put down the the mart once in a while, but on any track it would be a blast to drive.
