My 528 is nearing completion. It is a Mopar Mega block, with ported Mopar heads, Barton rocker system, Kellogg 4.150 crank, custom ground Comp 800+ 55MM nitrous roller cam, custom 4.500 JE 11:1 Pistons, ported Indy tunnel ram with (2) 1050 Dominators and (2) NOS foggers. I am hoping for 9's on motor in my 70 Challenger. Still all steel, full interior, all glass windows. (Still a Steet car)

Mine is rather head limited and peak hp comes in at 5782rpm and torque peaks at 4818rpm. I shift at 6200. It makes over 800ftlbs from 4100 all the way to 5500rpm. It's REAL fun on the street.Dave

Its not OEM heads, but there is a member here from Australia who has a stock stroke 440 with CNCed Stealths running high 10s in a B body who literally uses his car as a daily driver from what I understand. He's 252 @ .050 which is a bit hairy for some for a daily but could be done by many.

I already posted what I had that fit the description of a 440 with ported OEM heads that could run high 10s, so there is nothing bogus about that.

BTW, he didn't say "factory" 440, he said a 440 with OEM heads. [/quote]

It can be done, we have run 10.87 on a +.030 440 with OEM heads and a steel crank at 446 cubes....It takes work to do, and a good combination of parts. The car cannot be super heavy either and probably isn't the most daily driver friendly, but we have done it....With a stroker, the ET drops into the 9's on pump gas RB with after market heads.

Agree, we did it back in late 70s 440-.030 over 906 stock heads 800 dp 68 Dart, was a race car though, but could have been driven on the street. 10.80s-122 3040lbs.

Steet car days, 590 cubes 14/71 drive around at car cruise for 3 1/2 hours in 95 degree temps and never went over 170. Limited to 10 seconds at the track because of the cage then. Ran a 9.3 as a street car the last day of the season last run with boost turned down to 8 lbs, because trying 20 lbs was all over the track (they made me go down the track alone kind of crazy)

mine is a 606 cuin its a pump gas 12 to 1 compression hemi stage V heads barton single dominator intake in a mopar steel block it has run 9.60s at 140 mph in a 3910 lb charger on the motor on 93 octane !!!!! i just put all the parts in aluminum indy block that is 180 lbs lighter than mopar block hope to get it to the track this year !!

OK with ported heads and a stroked 440 but at what car weight? Not arguing, just trying to get an understanding.

I bet that bad boy is a heck of alot of fun to drive on the street. Ron

I built this 572" for pump gas street / strip use. World Alum. block, Stage V heads, ported by MCH, 10.5 CP pistons, K1 crank & rods, Indy intake, Stage V rockers, Dwayne Porter spec. Comp solid roller that is on the mild side for longer valve train life.
So far I am pleased with it. I had to sit out last season, will be back this year.

Just curious, any idea what a Alum block, Alum head Hemi weighs?

572" hemi, KB block
MP heads ported by MCH
Dwayne Porter spec'd solid roller...276/284 at fifty, real mild lobes to be easy on parts
Barton intake, single 1200 cfm Dominator
11:1 compression for pump gas
727 trans, 4.10 Dana rear, drag radials, Cal-Tracs

On motor and on 93 octane pump gas it has been 9.50s at 140 mph at a little over 3800 lbs.

On a little nitrous and at 3900 lbs. it has been 8.95 at 149.7 mph. It'll definitely go faster...been pretty conservative w/ it so far.

Pro-tip: Buy a Challenger Hellcat, A8 trans, swap the supercharger pulleys, get ECU unlocked and buy a tune. Buy a set of wheels and mount some drag radials. Drive it daily and grin. Mount the drag radials for track day. Enjoy the A/C, premium leather, satellite radio, heated steering wheel...
It'll be more comfortable at 135mph than your 70 Challenger at 80mph.
disclaimer: I prob have hearing loss from my Barton 528 solid cam clatter.

1969 RR with 572 Hemi.
StageV heads and Modman intake .
F&B performance sixpack system regulated by XFI 2.0

Complete carb to pan should be right around 500lbs....
