Very pleased

Max pull was made by holding 6,000-6,100 rpm and
taking a snap shot reading.

Normal run up and release pull gave 468hp at 5,900 rpm and 433 ft/lbs at 5,400

Equip list:

351W w/ .03 over bore
AFR 185's w/ 10:1 c/r
CompCams XFI 236HR-14 cam
Windage tray
Long tube headers, VicJr. intake, 750 cfm carb.

I will be running it with TrickFlow EFI though

mine has stock crank, stock rods, forged pistons with 13cc dish
with ARP bolts and main studs.
Also added an FMS windage tray.
with 58cc AFR heads this made right at 10:1 compression

If I were you I would call camshaftinnovations.com and get
a cam/head package from them.

You would get the right cam, the right springs and they
sell Canfield heads.
After seeing flow charts I wish I had gotten Canfield 195's
supposedly they cost less too.

hmmm, not bad for a 357 ... is that what you were looking for? sounds like a pretty mild build up to me. i'm looking for more like 450 at the wheels out of my 410 build, which translates to closer to 530 at the crank. i'm going with 205 heads and a custom cam.

is it for the street?

was more than expected, figure after i install it and put real
exhaust on and an air filter and p/s pump and all that other shyt
I should have a solid 450hp to play with.

was hoping for 425-450 so I'm more than happy.

Know some one has a 408W w/ AFR 205's and carb he
puts down like 430rwhp.

You should be able to get close


and yeah this is a pure weekend street brawler.
