"Butchers Special" Engine
I posted in the sticky section too.
Its been a while since i built an engine and I have a nice collection of parts on the shelves, in the barn, etc. With time catching up to me, I figured I would put some of them together. This is not a MAX Effort engine, but a pump gas street engine. My goal was to keep it below 600 HP, closer to 500. Best I can figure 9.9 to 1 CR -69 400 block +.060 2 bolt with Studs, short fill with Pontiac Dudes filler -Stock crank .010/.020 -PPR Ultra Lite Rods -ICON -14 cc dished pistons and Total seal Moly rings gapped for spray. -72cc E Heads CNC ported to 325 by SD Performance. Upgraded to 2.19/1.77 valves. -Crane Solid Roller 236/244 @50 1:65 rockers making about .600 lift, degreed straight up. -Warrior Intake -Milodon 8 QT pan, crank scraper, windage tray M-54-DS pump (60 lb) -GMPP 502ZZ EFI wiring harness with MEFI 4a PCM, Fast dual sync distributor and a Fast 4150 1000cfm Throttle body with (4) 100 lb injectors. -Heddman Hustler stepped headers -I built a test stand and it fired right up and idles well with the small SR cam. After I run it a little, it will go to the dyno at Smittys Engine and Trans in Vasser, MI for tuning as smitty is a master at tuning the MEFI system. I used the MEFI because I am familiar wth it from a couple boats I had. Its not as good as the new stuff but adequate. Comments are welcome! |
