I still got 2 451s and they both have run 5.49 at 265mph 15 years ago.

And I never drained the "breakin" oil lol before running them. I have never changed the original oil in any motor that I built or any motor from a car factory.

I have made more power than anyone on this board.

Thanks I'm trying to get a feel of about what my old turd should do ..hopefully I'll get it out this year if not I'm going to sell it and move on to my street car..

I was wondering the same thing...

I'm debating a 451 also. So let's hear more

Something must be in the water I'm on the fence about selling mine

Lol well went through a divorce and and now property fight..i. self employed I own a couple dump trucks that keep me busy either working or working on lol.. would live to make some passes even build a new bigger motor I just have to get back in it..life will beat you down sometimes..just have to figure out what matters the most now days..

Sorry to hear about your situation the nice things about Race cars we can push them in the corner until whenever

First off....there weren't many 451 low decks around (only in magazines) back then but.....I had a 383 rod 451 Low deck back in early 91's, home ported big valve 452's, Venolia zero deck flat tops, A Lunati 30307 520/547 lift 240/250 @ .050 duration with an M1/worked 830 Annular and 2" Pro-parts headers mated to Flowmaster 4-2-1's phased at 180. It had a 10" Fairbanks that stalled around 3400 and a 3.91 8 3/4 with McCreary Dirt Track tires. It was in a 73 duster and it ran high 6's in the 1/8th at about 100-101. Really quick for it's day as a street car and for what it was.

I had a Weiand Team G on it to try and it dropped off like 3/10ths, tossed that boat anchor in the drink. Thing wouldn't fall out of a tree with that manifold on it.

I'm not sure. I bought it uses with a bunch of parts

It's a Comp 308R

I added a set of Hooker Comp headers.

It runs a 11.55 @ 115 mph

My prior motor...rb 451 with stock crank and rods. 10.6 comp forged pistons wiseco, with lightly cleaned up rpm heads with rpm intake and mp 557 cam. In my 68 charger at 3900 lbs, it ran consistant high 11.30’s to low 11.40’s at 119-120mph. Thats with manual tranny and 4.30 gears.

Late 90's built 400/451. 12.5-1 Ross, eagle rods, 440 crank, comp 660 roller, ported Indy SR,Indy intake, 1090 demon, in a 71 Demon, street trim, 28", full exhaust, 3350lb, went 10.0 at 133.

A little different combo:

451 SMALL BLOCK

4.100" stroke x 4.185" bore

hopefully north of 900hp N/A

'71 Demon at 3000lbs

Should run in the Mid 8's

That's not fair.

All is fare in love and war.

440 .055 over.
Just shy of 4100 with me
Best of 10.88 @ 123.
4.30 Dana with spool on 30x9 Hoosier
8” PTC with a low gear set 727.

Here goes the build.
