NHRA currently has both the low and high comp 63 Maxes rated at 409. After questioning the power advantage to someone who had done a lot of homework on it I was told maybe 8 HP if you run C-25 and have everything perfect, I decided to stay with the low comp with my new shortblock.

That looks like a decent pattern, the backlash is controlled with a spanner wrench on the carrier bearing adjusters. You start with about zero backlash and then add preload to push the ring gear away from the pinion which gives you backlash and bearing preload and then fine tune. If you don't...

No single four 413s in any 62 B body, the inline four 413s were Dodge only.

Most of the NHRA stockers required to run flat tappet cams are running billet cams with Trend tool steel lifters. The good cast cam cores that Comp and the others used are no longer being made or available.

Check out James Gang Live, Joe at his best.

Yes, but 500HP is another story.

Not without aftermarket heads or some serious porting on the stock ones.

Whoever set that up should be smacked.

You can get light weight pins in a 1.094 and cutting the stock ones down to 3" will bring them from 225 to 190ish.

I hone the piston pin bores to give 12-13 tenths clearance in a pressed pin situation, it's a lot better than the 5-6 tenths they come with, that said the Molnar rods are the best deal out there for a great set of rods.

I put them on many 62-65 street cars back in the 70s-80s with low and raised blocks and would buy 68 Road Runner pipes from the local auto parts store, never an issue.

I just balanced a stock piston 383, Bob was 2460 and a 440 with 2295s using stock pins so very close to stock, Bob was 2580ish, might be off a hair but the notes are in my shop, I'll check it tomorrow.

I've been drag racing BBMs since 71 and spun a bearing in 74 and again in 94, never any other engine damage. I've known many people who could break anything in short time.

They will not hit the head.

I used to write tech articles for High Performance Mopar back in the mid to late 90s, they were mostly cylinder head based along with flow bench numbers. It was a lot of work without the internet we have now, sending pics, all Tri-X 400 and having to fax back and forth for me to proof read, it...
