What head I ask is going to do him any good at 7500 in a bracket engine? Why plan an RPM level--see what cam will make the car 60 ft hard and be right for car weight and the compression ratio--oopos! Too much compression is a bummer in a small block with 10 head bolts better plan on head gasket replacement often--now THAT is a weak spot on a small block not the darn oiling! Then with 7500 you need really lite valves--titanium retainers, PAC springs and very light strong rods and pistons--and Real expensive rockers-- all very expensive stuff OR--you can just hang a set of lite pistons on stock rods on stock crank and turn it 6500 range and have a CHEAP FAST reliable engine
that will make hundreds of laps over years with zero issues
OK 7500 RPM--a head that can make use of that on a small block is not cheap --and when you dyno them 6500 vs. 7500 is the extra cost WORTH the extra HP vs. the lost reliability?????
It is fun to twist the guts out of an engine--I always thought JR Johnson was an Azz but he said one thing I loved--He said--Give me an engine that will never quit going upstairs and I will whip anybody--He had a need for that--average bracket racer does not
That baby seat in the back of the slant 6 car is what hurts the most at the turn off road
