What if.....

[theman440]

Mega-block 4.5 inch bore. 4.15 crank de-stroked to 4.00 - 509 ci. 7.2 inch Crower I-Beam rods, 12.5:1cr Ross or Arias pistons, external pickup, tray, scraper. Edelbrock Max Wedge heads, Jesel belt drive and rockers. Big solid roller, Indy Max Wedge Cross ram intake w/dual Holleys

You must lie revin them to the moon.Short ashtray pistons and tunnel ram = 7000rpm shift points:headbang:

Turned a 440 stock stroke 7300. It ran 300 passes and a valve spring finally gave up. I knew they were tired but there was one more race left in the season and well, oh well. The engine didn't come apart though. Was really lucky on that.This 400 should be looking at 7500 at least. The 440 was a tunnel ram engine too. I really like them.

Cranky, are you saying a 400 block and stock 400 crank with the 440 rods? Any major machining besides cleaning them up? Also what cube will that give you? Thought everyone did a 440 crank and rods and went for the 451 inch motor. Curious though as I will eventually build a budget stroker. Thanks.

The 451 is a good combo for sure. I'll be using a forged 383 crank in the 400.

It will still give you 400ci,but the long rod gives you a very short piston.This will greatly decrease recip weight and decrease piston drag.It will increase your rod ratio wich usually increases hp.The idea less weight and drag to increase hp with rpm.It works very well,but for short periods of time.Dual purpose motor it is not,well lets say not for the average joe.Alot of old 4 speeders used this setup to turn them 8000rpm.In the local detroit area their was a few around setup like this.

And I have a Jerico 4 speed hiding and waiting. This stuff has been laying around for a good while now and it's time to do something with it. I have most of the parts I need and just need to get going on it once all the other honey do's etc are done...
