Serious 340 build into 361 HiRPM Screamer

To answer the Q’s on my 340......

-Gasket matched Victor with some mild plenum clean up
-11:1CR
-587 heads with basic full porting. Flowed 260 with 3/8” stem stock replacement 2.02/1.60 tulip valves
-Custom Ross flat tops with .927” pins.
-reworked unbushed 360 rods, that had the beams polished and were fitted with ARP bolts and bushed to .927”.
-1-3/4” Hooker headers

There were way fewer options for off the shelf trick parts for a SBM in 1991.
