5.3 and forced induction option’s Good morning guys I have a 5.3 that’s been bored and stroked to a 3.63 the engine has Cnc 243 heads that are suppose to flow 307 cfm at .600 lift I’m running eagle crank eagle h beam forged rods dss flat top piston with Vaule relief I’m looking to go with forced induction I don’t want any lag I would like it to be as responsive as my accelerator pedal the goal Is 850 hp at the prop what would you guys reccomend
That response you're seeking can be had, but like N/A engines, you have to treat it as a 'System'. Your cubic inch, compression ratio, cam choice, torque converter choice, fuel choice, gearing, turbo, vehicle weight and tune need to be considered as a whole for optimum results. You can do like I did, wasting money, time, hours and hours of fabricating hotsides, cold sides, several different turbos trying to get murderous power. Right now my 315 drag radials spin in all 3 gears (TH350) anyway.
But if you like working on your car , just dive in with something and try it. There's no 'right' answer.

Ah.... if that's the case, a buddy of mine put a 7675 turbo on his 416 cubed, big cammed LS3. As you can imagine, it spooled almost instantly but quickly 'fell over' by 5K rpm. Just too much exhaust between the cubes and the big cam to get thru that little 75mm turbine. So he swapped with a guy that had a Procharger on his '02 LS1. Steve got the procharger and the kid got Steves turbo setup. Steve installed the Procharger(easy installation compared to the turbo kit), had it tuned by Jannetty Racing and got 734 rwhp out of it right away.

Verdad Gallardo So with that type of prop, response isn't really a huge issue. You'll have a huge delay between pinning the throttle and getting max speed on the water. You'll just be able to run a lot more pitch with more power. Pair of 61/65s all the way up to 72/65's would be fine. And cost Roughly $280-375 each.
