Things seem to be going slow on the forum. Maybe this will help get you guy's fired up for the approaching winter.
This is not my motor, but I did supply the majority of the parts.
320HP and almost 290 TQ. The tq curve was almost flat after 2800 rpm. The max HP was also achieved at 6300, which is where the dyno was shutdown. The HP was still climbing. We figured it better for the owner to find the top HP on his own.
It will have a pretty nasty idle and is more cam than is needed for 300 HP.
The build:
250 bored .040
Honed with deck plate
Block zero decked with pistons
6" Scat rods
Flat top Ross pistons
Balanced rotating assy
About 10 to 1 compression
Head work included
1.94/1.60 valves
Bolt in HI-FLOW lump kit
New guides
Hardened exh seats
Milled .030
3/8 pushrods and guide plates
HD springs rated for upto 7000 rpm
1.75 Roller rockers
Cam By Crane, 224/230 dur @ .050 .550 lift
Dist- HEI built by Autowerks
Clifford Intake
Edelbrock 500 AVS carb
Full length truck headers
Valve cover and side covers by Autowerks
This engine was a blast to dyno and will certainly be fun to drive. It is going into a 1968 Chevy 1/2 ton pickup. Believe it or not, with a 3 on the tree!
The better runs are at the last 4 minutes of the video. The video could have been edited , but it was not fair to not show things that really happen during dynoing. There was one pull done with the camera in the dyno room. The camera shut off because of nothing seen moving, just lots of sound. Grrrr.
You will also notice in the video how hot air is not your horsepower friend.
