I’m 1200hp+ at the tire and 3900lbs. If you wanna do something, talk to the people that are doing what you want to do. You’re challenge will be that clutch and manual transmission. The only thing I’d add to your combo is a programable digital ignition like the MSD 7531. You could easily manage...

I’m going sub 5.50 1/8 mile/ 8 second quarter mile times on a 275 street radial and leaf springs. You don’t need big tires and tubs or fancy rear suspensions.

He’s a good dude. I chatted with him at Drag Week a few times.

Clark Rosenstengal?

I fabricate nearly everything I need...including headers, cage and even the front suspension.

I know it costs a fair bit more, but I prefer to mill off the cast in stands and use individual rockers on a bedplate when the application allows. They’re shim-able and allow for easier accessibility to a single pushrod or valvespring.

Diamond Pistons in this one

They’ll physically interchange and, as indicated above, the 440 has a larger main bearing bore. The ability to swap caps from one 440 block to another depends on the accuracy of the main bearing bores between the two blocks. You can cut caps and align bore and/or hone depending on how much they...

Not to derail the thread, but what’s the story behind the breather extensions? No baffling in the valve covers?

Slowly rotate the engine until oil starts feeding out the rockers on one side. Then again until you get it out the other side, lol.

Why not just leave it a 400 if you’ll be adding the turbos? Change the crank out with a forged 383 if you’re worried about it. If you find a good take out, that would also be the least expensive option. I’d add some ARP main bolts, bolt on the turbos and send it!

Car went 9.97 this past Saturday with a 1.4 something 60’

I built this one a few years ago using the 240 heads (the 270’s weren’t out yet) and it’s been low 10’s in an A body with a horrible 1.8 sixty foot. The six pack tunnel ram kept us from 700hp. 537ci Really Sic Pak Wedge with Trick Flow Heads

It all depends on how formidable it needs to be in the 1/8 mile. I think most assumed it was more street than race. My choice given the cubes and a cross ram, would be a hemi.

I had a hydraulic roller ground for use in a 48 degree R3 block so a BBM is an easy one. No, probably not gonna be 800hp in street form.

They work well with good lifters like a Morel, however, the one mentioned is quite small for a 572 cube engine. The 270 head would be a much better choice for this combo as well.

No. You don't need external oiling for a street car.

I just did one last year using 2.200" rod journals and steel H-beams. Just a little clearancing on the oil pickup boss and all is well. Going to external oiling is added pain and expense and usually not needed.

Are you using the same intake for testing the 270?

CnP Mucho bettero....this one will also be DBW as I'm ditching these throttle bodies.

X2. 4.250 bore and 4.500 stroke is 510 cubes and will easily make your goals. Other than having those heads checked out and making sure the guides and valve job is right, you shouldn't have to spend big money on porting to make that kind of power. I'd get a StageV intake or at least a dual quad...

Did you check for a broken inner valve spring?

Throw that cam away... it's way too much cam for that engine. You need something in the [email protected] range and it'll sing. That combo would be lucky if its got 8.5:1 CR.
