D150 with a RV 440, just to see what it will run

-
.510 ish is plenty of room for what you’re doing. You could leave the 4.30 gears in and change cams and pickup at least a half second without fast ramp rates. The broomstick looks like it was designed for a school bus governed for the 45 mph top speed law.

I need to get in on this. The combo should be in the high 15s but you have proven your ability to get the most out of what you have. Put me in at 14.89.

I have you 1 second better than most. If you do 1.5 to 2 seconds better it’s time for me to put my Mopar performance engine book up and get out the suspension book. On second thought, time to do that now!

Then it'll get outta the hole quick. Then die. LOL

Look at Comps version of the Road Runner cam. It's more modern faster lobes and it's ground on a 110 instead of a 115.

You still won't know. You're running non stock intake, carburetor and headers. You've not measured the cam, so it "could" be non stock as well. Did you measure static compression? Now I'm in no way knockin what you're doin. I love it. I know you're trying to get as close a base line as possible, but the engine is not in stock form. It has bolt ons and they count as modifications. It wouldda been "difficult" at best for me not to have had those heads milled .100" and had the intake cut to match...but I totally get what you're doin here and love it. You show great restraint. LOL
 
Ye'all be talk'n in your sleep.... stop dream'n.

I can't stop laughing! You can do it!

Will there be a protest from the members and teardown if the Ol' Fo-Foty breaks into 13.99 territory..?
 
I couldn't help myself...

You have a valid point about the internals and "blueprint" of the current configuration. He's seems very honest, but now and again... there is really know way to know as you've stated.
Well he hasn't run it yet. Is it really stock on the inside? Probably. But it's unknown. Regardless, it's a fun badass project and I'm lovin every minute of it.

The guy I bought it off of removed it from the RV. Remember, I did take the heads off, and yes, I've seen the cam. It was a stock as stock could be RV 440, I was the first one into it as the gaskets were factory. And it ran in the magnum, and ran and idled like a factory '77 New Yorker... LOL Yes, it does have a different intake but the factory cast one is on the floor right beside the engine. As far as I'm concerned, the factory cast with a good TQ might even run harder at the track, who knows. So in my opinion, we'll know. If mine does it, anyones RV440 can do it. :)

I get the feeling that you may know someone who has tinkered with a motorhome 440 before… according to the Stan Weiss compression calculator: with the pistons .170 in the hole (that’s a thing with motorhome 1.912 compression height pistons), worst case chamber volume of 90 ccs with 7 ccs reduction by .030 cut (83cc’s), and 4.55 bore X .039 8519 PT-1 head gasket, we’ve got a womping stomping 7.7:1.
