Re: SAM's SB2 At The EMC And The REC

Here is a nice 420ci, developed by HIGGINS race heads in Australia made 864hp @7500rpm and 640tq on PUMP GAS. =D> The Heads are 2.85 mcsa and with a 2.170 intake 1.6 exhaust valve. What makes this even more impressive is that it’s done with 4150 manifold / carburetor. https://www.facebook.com/732945...
