I have this good .030 over 1968 400 block sitting around begging to be built.

Already have some old style 325cfm round port 87cc E-heads and Torker II intake.

Going in either a 1st gen or 2nd gen f-body that will see lots of street duty but also about ~6 autocross and track (road course) days a year.

Having had a 4.25" stroke 461, been flirting with trying a 4" stroke crank in this block just to perhaps try something different and rev some.

Will be forged crank and rods, roller cam, hydraulic roller lifters. ~10:1 CR.

Love to hear what I can expect from a 4" stroked 400 vs the more commonly seen 461 build. Plus and minuses for the application. Cam I should consider etc. Thanks in advance.
