Tunnel Ram on a 383

Good luck with your Tunnel Ram
Last time I ran one was in 1982 in my F/MP 1966 Chevelle
301 ci 680 lift 290 duration @ 50 roller cam, 14 to 1 compression , hemi 4 speed pro shifted with 6.17 gears -tunnel ram with 2 800 cfm holleys

F/MP? Wow, I use to love the Modified Production class! John Dianna with his tunnel-rammed small-block Duster that use to reach for the moon every time he launched was my ATF in MP.
