what would you buy?

lunati bracket master II
285 455 2000-6000
290 460 2000-5500
292 480 2000-6000


this is a 350/290 hp rated gm crate motor with a performer rpm air gap intake and a 650 quick fuel carb. 1 5/8 headers.
i did install 1.6 ratio roller rockers and this will affect how this cams specs are so this is why im asking.
transmission is a 350 turbo with a 10 inch 3500-3800 stall and 4.10 gears
im not changing anything but the cam and lifter and the springs will stay so i dont even know if the bigger lift one will work. thanks for the input.

292 it would be 512lift w/ the 1.6 It should be peppy and sound good plus with that gear and stall ....You will have to be carefull with the retainer to guide clearance though.Springs will be easy to find too..depending on the head you might not even need to worry about the guide clearance...

i wondered what the lift would be. i just dont wanna get into springs right now. i have got away with a 510 lift on stock springs before. but i dont wanna go that big if i can get the similar hp out of the next smallest plus i dont want a lot of thump. gives it away...lol

I ran a summit 1107 I think it was, for years adn it worked real nice in my 10.1 sbc with 1.94/1.60 64 cc heads. I think the advertised specs were .488/.510 and 292/302. I had 1.6 roller tips on and never had any issues. You could drive it all day long.

speaking about compression this is only a 8.5 to 1 just to throw that out why we are on this.

Call Bullet and have them recomend one for your application. Wont cost a dime more. Better than some generic shelf grind.
Took the words right outta my mouth!!!!
