This is the list of engine parts in my engine im tryin to figure out the best fuel pump, regulator, ghp,psi, and carb to run. If any one can add anything else to any other aspect feel free too im open to suggestions

350 ci 4 bolt steel crank
142 wiend supercharger with 5 to 6 lbs and 9lbs for drag
hbeam rods
forged 21 cc pistons
trick flow 23 degree heads 72cc chambers
flow on heads int:256 exh:186
cam: lift int: 488 exh:510 Dur at .050 int:234 exh:244
lobe seperation 114
msd box distributer and coil
maybe 100 shot of nos if my engine doesnt make over 550hp
I was thinking about going with 850 speed demon and black body holley fuel pump with 9psi regulator

how much HP do you think this will make?

 

what compression? Below 9:1 i hope. Anything over and you will lose horsepower. Why? well for one, 114 LCA is a "super Charger" cam, will trap alot of pressure, alot of torque will be made from the boost, but alot of detonation will be made if your trying to squeeze all that boost into a tiny chamber. The only way to combat detonation then, is timing, and that hurts worse, better to go without the boost than timing. taking 6* out of your advance can cost you more power than taking .5 off your compression ratio. with that cam and 8-9 psi i would say MAX 8.5:1 ratio. thats the safest, conservative way to see it. without the boost though, the engine will be a dog. if will make a hell load of low end torque, take out some duration and the car will idle LOWER and sound closer to stock than you think imaginable. it will also have better street manners with less duration, and you'd only sacrifice some top end horsepower, but not much. I estimate about 500-600 horsepower if it holds together, with alot of initial advance, around 28* but no more than 32-36 total.

 

yea i calculated my compression to be around 8:1. Have any comments on what kind of fuel pump and ect i should run?

 

fuel pump? Electric carter or holley. you have the right idea, and get a good fuel pressure regulator. dont worry about a return line, in my experience the electric fuel pumps dont really care. As for the carb, dont go below 750 in my modest opinion. Too small a carb will actually restrict air, and the engine will suck fuel instead, creating a RICH/RICH condition at all engine speeds and you will lose power due to lack of air. This is my current problem, a 650 double pumper just not enough air, too much gas. Mechanical secondaries is the way to go, and 850 may be just right. you'll have to experiment tho... as for fuel pressure, im running 7.5 PSI which is too much but i have no regulator right now, so the pump just goes full out whatever it can dish. for a blower setup i would say 6-7 psi I suppose... just make sure you dont lean-out at WOT because of small fuel lines from the tank or somthing silly... just because you have high fuel pressure doesnt mean your feeding a ton of fuel. size DOES matter, in this instance, especially concerning fuel lines. although with 9 psi of boost, on a mini blower like that, stock fuel lines should do it I am told... Im building a similar setup... How much did you sink into the engine? Im curious how much i should save up before i begin... and i notice you didnt stroke it... any particular reason? it couldnt be cost since a 383 stroker forged crank is almost the same price as a forged 350 crank.. what gives?

 

I wish i had a 383 crank but i dont and i had a 350 forged crank laying around the garage so i decided to go with that because im hurting for cash for my driveline. In the future i am going to go with a 383 stroker but i figured i would get the motor running and after im done with all the other aspects of the car i would switch to a 383. I was told to run 9psi you think thats too much? 140ghp should be enough but thats just a guess. Will an aftermarket O2 sensor for fuel mixture readings fit into the stock o2 sensor whole? I was just wondering so i could make sure it doesnt go lean then have it go kaboom
