Response to Horsepower/torque guess?
Just finished a back to back Dyno test for a customer.
351+ .030" my new heads vs Iron 4v's. Full exhaust system ,2-1/4"engine mid pipe & muffler ,2" tail pipes!!!
Stock un ported 4v closed chamber heads, f238 solid.
397hp 401 ftlb. Peaks around 6000rpm
My new SCM 4v's
Timing from 36*iron head to 29* my head no other changes.
Very very basic engine! Built 20+years ago!
Yes Iron heads can be ported to work very well but then you would have to
Wait for someone to do that! Where as mine are ready to go . Lol.
