Ok Gents lets all play Nice NOW!

Lets keep it to the facts.


The original intent of this post was to establish a game plan for a smaller 433 CID BBC with forged components matched to a Solid Lifter Cam, Single 4 or Tunnel Ram( Edelbrock or Weiand), High Compression Pistons 11.25-12.5:1( but a 13.1:1 might be better), operating RPM range 2500-7000(shift point 7500).

Fuel should be Pump E-85(96-105 octane) spiked with 25-30% Rocket Brand E-85(112 octane).

Desired output at the flywheel is 600-700 HP with another 175-400(single or dual foggers).

Rear Tires 31-18.5-15 ET Streets, Dana 60 rear 4.88 gears with ARB or Detriot Locker, Transbraked TH400 trans.

If I could accomplish this with lower priced components like Patriot or Procomp heads, a 427 tall deck production block over AFR heads & World Blocks then I'll be ahead in the long run.

I just want to be eyes wide open and see the true costs I will need to pay.

Thank You all for your Honesty.
