Input towards new Engine!? Just wanted to throw this out and see what you guys thought of it?
http://www.ellweinengines.com/Ellwei...Components.htm
With my current ported heads, intake & cam:
Ported by Jason Short in NY. they were completely broken down by my machine shop. They flowed right around 255cfm at .500 lift. Chambers are 54cc's, valve springs are comp 977's with Ti retainers and locks ARP studs and Comp 4084 guide plates. Before they were put back together the valves were lapped and seats cleaned up. I don't know what the installed height of the springs are off hand. I belive they were set up at 1.800 so they should be good for .600 lift. I'm using Mr. Gasket .026" gaskets. The intake was also ported by Jason Short. Nothing real fancy just a basic port job on the runners and the TB was opened up to 58MM. Finally the cam is a Comp Cams "306" LT1 Camshaft, 230 / 244, .510 / .540 112 LSA
With these top end mods:
-Comp Magnum 1.52RR
-Comp .0072 Chromemoly Push-Rods
-Stock Lifters
-Comp 977 spring
-Comp Ti +.050 retainers/seats/locks
-ARP 7/16 studs
-Racetronix 255lbhr Fuel Pump & Hot-Wire kit
-Lunati Double Roller Timing Chain
-GMPP EGR Block-Off plates
-Enlarged Throttle Body Opening (sized for 58mm throttle body)
-Stock ported Throttle Body
-Meizer Electric Water Pump
-!AIR/EGR
-Throttle Body ByPass
All I would need now is a different oil pan & a good oil pump.
