Haibeck 440

[Hammer]

Anybody else catch Frank's new signature? Come on Frank, tell us about it. =D>

Lucky fella you are, Merry Christmas.

Wow, a 440 . i wonder what size the pistons are? and the crank I wonder if they are using the 415 crank. and what the rod stroke ratio is . ah I could never afford one but its xmas and one can dream

Hammer, there is possible talk of trying to go up to a 454. Marc did a phenomenal job on this project. The motor was in the car and waiting to be run in and tuned the last I heard of it last week. There are two other indiviuals waiting to see if the 440 yields any more substantial power a 415 and they will be doing an engine as well.

Any chance they'll be dumping those puny old 415's afterwards?

i've wondered why LT-5's haven't gotten very big in the aftermarket circle's? i've built a couple 340 based Mopar small block's a little bigger cube, one was 461 cube & the other is 465 cube. i also did a 426 about five years ago but that's nothing too crazy. all based on production block's, no spread pan rails & no raised cam tunnels, also standard 340 deck height's. of coarse nobody thought i could make it happen ( INDY ). don't have too worry about raised cam's in the LT-5's obviously. not trying to step on any toes but from what i know & have seen i don't think mid-450's is a stretch with out-side of the box thinking. once you start getting that size the head's are usually the next problem on a two valve set-up. four valve shouldn't be a problem though.

Wow. Great news! Does Marc use the EES big liners, or did he design his own? What cams did you go with, Frank?

What is amazing to me is over 20 years later and still more ground breaking mods are being done to our beloved LT5's ie. STS turbo's - unreal turbo combinations - bigger inch's. Also the guy's that are involved with the LT5 engines , tuning etc. are all diehard LT5 lovers. It is still a great time to own a ZR1 !

Thanks a lot for the update Frank. It has got to be great to be able to put a project of this magnitude together with such an LT-5 Guru as Marc. Truly phenominal (sp), it should keep our cars on the forefront.

Are there any magazines interested or have they been approached at all? I can't wait to hear how your car runs.

So here is what I wonder then. Instead of the budget 368 build, will a 391 build be the next thing for stock-crank builds? If it cost about the same as a 368 build-up, that would really be something. Just doing some basic math, if a full-bore 350ci motor makes ~430whp, a 368 would scale to ~455whp. I don't think that's too far off a stock-cammed 368. But a 391ci motor would scale to ~480whp. That's a lot more bang for the buck, assuming of course it's possible.

I can't wait to hear more about it, and of course to read the whole deal from start to finish in the next Heart of the Beast magazine!

The bore spacing will be the problem with going over a 454 as it is getting kind of thin with the 4.125 bore. Then again the deck height can be raised for some more stroke.

Thanks for your interest. I'll keep you guy's informed on the progress.

What type of intake are you doing?
