Got a stock 408Sbc bottom end with L31vortec top end 770 Holley ultra avenger big MSd pro billet and 1 3/4 full length headers.
with the cam fitted and the dished pistons it came up at 8.5:1 and it hauls *** on pump gas. And runs hard at 5500Rpm all day.


I have a bottom end that is more or less a 300hp setup and the top end could support 500hp.
The Dart 427 SHP looks like a good thing and i could bolt all me gear onto it and get e new cam ground to suit the compression..


I may have to talk to Dart about dished pistons as the ones that are stock in there short motor require 76cc chambers to keep it at 10:1 pump gas capable.


Has anyone bought one of these SHP 427 short motors. Apparently they come with either Scat or Eagle rotating assemblies depending on whats available at the time.

 

I have one in my car. Very happy with it. Eagle rotating assembly. HSR intake, 30lb injectors, AFR 220's, XR294HR can, 3600 stall. It moves out.
