Whats your guess on my hp?

[streetstang67]

What would you guess I'm making for horsepower at the crank?

Factory "C-code" 1967 289 block, rebuilt to stock specifications except for the following:

Holley 600cfm vacuum secondary carb
Edelbrock Performer intake w/1" open spacer
Crane XR-i Ignition
MSD 8.5mm wires
Comp XE256H Cam
-lobe center 110
-lift: .477,.484
-duration: 256, 268
Multi-angle port/polish job on factory '67 heads
Stock valves (1.77, 1.45) with springs to match cam.
Comp magnum roller tip rockers (1.6:1)
Stock style 3-row radiator
flex fan, alternator, and A/C on the belt(s).
Hooker comp headers (long tubes)
H-pipe w/dual Flowmasters


I dynoed the car a while back and it produced 187hp at 5200 rpms at the rear wheels (guessing about 235 hp at crank)...but I think the car was out of tune and could do better. What do you think?

thats a a pretty mild build for your engine, so 235HP is probably about it.

Your heads and intake are really going to hold you back. A RPM/Stealth and some aftermarket heads would really help and you wouldn't give anything up (except some $$).

I agree, 230-240bhp is probably in the ballpark.

Was that 187rwhp through a manual or automatic?

automatic (c-4)
