400's are they any good?

The 400 is a great block. You can throw just about anything you want to at the 400 block, with just main studs installed. I've a 400 shortblock in the storage room that we are in the process of detuning. It has run as high as 787HP with ported Edelbrock Performer RPM heads, single Dominator, solid roller and 93 octane. All motor, no bottle, no boost.

I guess the url won't post because of the space between the letters in "topic". The engine is listed on dodgecharger.com under 'proven engine combos', 451 with 500+ tq from 3500-7500+ rpm
