I picked up a barely used Vortech YSi from a buddy of mine and I'm installing it on my 30 over 454. Heads are mega ported 781s with bigger valves, small pop up pistons with about 9 to 1 compression. Cam is 240/246 @50 560 570 lift on 112 lsa. Carb is a Quick fuel 850 blowthrough and I'm using the EV hat instead of the box. With nearly the same cam this engine went 11.77@114 in my Monte straight up. With a 150 shot it went 10.99@122. I'm keeping the 3.55 gears but will step up to 28" tall tires instead of the 26" I ran the previous times with. It should make between 6-8 psi of boost. What kind of times do you think it will run? My 60foots need a bit of work best so far has been a 1.59. I'm hoping for a 10.20 or so, but time will tell. Happy New Years guys!!!!
