5.3 Twin Turbo Cam Advice First off, I am WAY, WAY over budget for this build. I won't be buying anything else for the car this year. So, It's kind of a this, or that question.
I bought a rolling shell 85 Monte Carlo SS, lightened it up a bit, then repaint ect. Here is whats in it...
LC9 5.3
Factory truck intake
243 heads cleaned up- BTR Double Platinums
Twin On3 T70's -twin 38mm turbonetics gates
Giant Air to water Intercooler, 4 gal tank 3/4 inch lines
Circle D Billet converter 3600
Rosseler Terminator 2 th400
8.8 out of a fox, 33 spline. 3.55 gears all Moser
15 gal fuel cell twin SX pumps (like twin a1000's)
10 an feeds to pumps, 8an to rail
1000cc injectors on E85
Megasquirt 3 running it all.
Now, ive got two cams that can go in this thing. One is a Texas Speed MS3. Quick67 on here had an MS3 with twins and says that his car was faster with it than 2 other cams. One a custom cut turbo cam.
The other is a Comp Grind that specs like this 238/248 .585/.595 113+3.
What would you guys do? I know neither will be optimal but, as I said I won't be looking at more parts till next summer.
Thanks for the opinions.

Yessir. Id rock 226/235 on a 113+3 in a twin MPT70 5.3 all day long and twice on Sunday.
Call Bullet.... Ask for Mark.... Tell him what you have and that youd like it reground to a 226/235 113+3.

The MS3 cam was pretty lazy, mine was a turd until it came into boost , but then it was an animal .I wish I had taken it to the track before I sold the engine.
On the trans brake probably would have been different .

BTR recommended me their stag 3 turbo cam (230/236 114+4), so sounds like the specs you were given to ask about a regrind would be pretty close and typical. sounds pretty good too lol
haven't gotten mine running with boost yet, but same setup as yours only im on stock heads and holley hi ram in a 78 malibu.
sick gbody
