Since things are a little slow around here I thought I’d share my build and my first outing experience.
First off the car is a 1974 ‘cuda 4 speed with 3.55 gears. It’s all stock except motor, wheels, tires, and scatterhshield.
When I bought the car 10 months ago it had a 360, probably built in the early 80s late 70s with forged pistons, w2 heads, strip dominator.
I decided to stay busy to help my sobriety (8 months now) and year the engine down and freshen it up. Well then I decided it’s a great time to add a 4” stroker kit. Unfortunately I got the scat cast crank kit since I was just building a mild pump gas w2 motor. Well then I find it’s impossible to find valves and didn’t want to invest in new guides and ordered custom valves.
I then ordered a custom solid flat tappet from Duane Porter that’s 251@050 and .556 lift on 108.
I srtarted getting impatient knowing my car may be down all summer waiting, so I contacted my buddy Del who’s a member here and asked if he had any heads he’d sell to get me going. Well he did. So now I have a 360-1 top end with intake and 1.6 rockers and I couldn’t be happier. They are bowl ported by Duane with a little short side work is all and flow 312@650 and 297@550 which is all I’m using. I put it together within a week at this point and ran it Saturday at Woodburn. The build is now as follows.
11.5 compression
251@050 and .558 at the valve after lash ( yes the offset rocker robs that much lift I found).
Indy intake
1050/4150
2” headman headers
4speed
3.55
275 Hoosier radial ( did not work well)
So with only 3 passes I managed a terrible nice easy pass since I couldn’t get traction.
2.163 60’
12.08@120.23
I am happy with the power it’s making my first time out with no jetting or timing changes and with some bias and gears and timing it’ll only get better. Yes I plan to upgrade the crankshaft this winter lol.
