Well boys and girls, we another one HOT off the dyno. Really, its still HOT as I type. This one is a bit of a stone soup type build. Its made up of some lightly used parts, and NOS things we found. These are the things you have to do to meet budgets LOL
So anyhow, here is the run down
360 block
Forged crank/rods/pistons
HP bearings
Eddy RPM head, ported in house, Stage 3
Old school Weiand Xcell intake NOS
Used crane roller rockers
Voodoo solid flat tappet cam 252/259
10.5 to 1
QF 950 carb, used
FBO ignition system
Kevko 5qt pan
Pump gas
Now for the good stuff. It idle well at 950rpm and pulled 10in vacuum with the vacuum advance hooked up. It liked 35* total timing all in at 3800. AF ratio was 13-12.7 to 1 the entire pull. BSFC was in the high 300's to low 400's. Plugs were clean, engine ran crisp and smooth.
Peaks
543HP at 6100
525TQ at 4600
Pulls were made from 3000-6500 TQ was already over 450 at 3000 and held that and more all the way to 6300. It also made 500+TQ from 4100-5600rpm!
HP was just as smooth and broad. Making 500+ from 5000rpm on up. It was still making 530+HP at 6500.
Im super happy with this combo. Don't ask about price as this was a special engine with a mixed bag of new, old and used parts. But you can not argue with the results. Customer will be happy, he asked for 525!
