Starting a R5/P7 build this winter.

I’m excited to get going on this one

it will sound a bit different. more compression and getting the cam ground. aiming to run bottom 8's

I'm kinda surprised how many of those motors seem to pop up, is it even possible to get cam cores if you wanted to do a new cam?
 
If buying used NASCAR stuff...be very aware that almost all teams did different things at different times. Lots of the various used parts, don't work well together.
Have a friend who went thru hell to get his working. It's a bad-*** car, though.

yes you are correct, it can be a nightmare. engine is complete.
 
There was a Dart on dragweek in 2019 that ran one with a stick. Jamie Passon was his crew. There was a video of it somewhere. Had to run unlimited because the engine was set back. IIRC.
 
There's s local guy selling his complete twin turbo R5P7 setup. It's taken a lot of self-restraint to not reach out to him about it.

I've always wanted to tinker with one of these.

my W2 engine was faster then that. must be 3600lbs to run that slow.

in the Omni it should run high 5.50's -5.60's

It’s probably 3000-3100 with driver.
Runs a glide, maybe convertor isn’t quite right, but it’s super consistent, he won the bracket final race couple years ago with it.
Have a buddy who went 9.40 at 143 with that deal with a 904 about 3000 with him in it.
Getting the convertor right isn’t easy. p7 deals I have seen don’t set the world on fire considering what the heads flow.
Chassis mods to get them to fit, convertor, headers, adapters. To me they aren’t worth the trouble. You can go just as fast with Indy heads, and come close with even Bloomers.

It's the short stroke that makes them touchy. J.Rob
