Cost of doing a 4.125" AES Liner Engine
Just to let you guys know, I was bored a few weeks ago & called AES. The cost to do a 4.125" sleeve shortblock using a stock crank offset ground to 3.75", AES supplying Pistons, Compstar Rods, new rod bearings assembled is $10500. This will give a displacement of 401. AES will plate the original supplied main bearings. Just thought I'd share in case anybody was wondering how much a complete shortblock would cost.

I guess I should have also added that if the better built 350's are getting 450 RWHP, which is 1.28 rwhp per cube, then 401 cubes x 1.28 rwhp = 515 rwhp & a very healthy boost in torque!

I think I would consider the AES closed block once you go 427 or beyond. There are plenty of displacement configurations below that with great power. A stock block LT-5 puts you into the 11s with DRs and a good driver.

YiKEs! $10k+!
I'll buy another low-mile Z first. |

I would think if I was considering a 415, 4.125" bore & 3.875" stroke, I would probably go this way.....big bore, short stroke, unshrouds the valves. Theoretically, it would be better than the 4.125" stroke.

Really makes it easier to a forced induction setup. You can get get fully forged 418 GEN 3/4 longblocks for under $4000 INCLUDING a brand new forged crank.
I does take dedication to pay for an extra displacement LT5. So far as shrouding of the valves, is that really a concern on the LT5? |

This is cheap.
Heck just a few years back a 415ci was $34k did not include cams or valves and if you wanted droped/siamised plenum well then your were close to $50k. So a turn key 401ci for around $15k is a bargain. Looks like a steal now. Pete |
