Forums : Performance General : 1992 5.7 tbi need 325 hp or more (279 Views)
January 20, 2007i would decide first how much money you want to spend...you could change out to a stroker motor....supercharge the one you have...will that be 325hp at the flywheel or at the rear wheel...to start I would go with MSD ignition and headers and a cat back system....and maybe a k+n filter or a cold air intake....good luck
January 20, 2007well gonig to buy heads intake carb,cams
just dont know what to look for to get me to 325-350 hp at wheels
January 20, 2007edelbrock's top end power kit (vortec conversion, heads, intake, cam) + a decent carb or TBI... forced induction (super/turbo charger) or N2O will all help..... add the CAI and a full exhaust (Headers, hi flo cats, cat back)... then you need some decent gears.....

January 20, 2007i have 4.10 in right now any parts numbers please
January 21, 2007Take your heads to a machine shop, have them port them and you will be astounded. vortec heads flow better than a lot of aftermardet heads. Have your exhaust valves back cut 30 degrees inside the 45 degree seat. Also have them mill the heads down a smidge, taking off about 2 to 3 cc for definate flatness of the deck Use the thin Fel Pro gasket which is about 0.15 inch thick. Also; on headers, go with 1 5/8 primary long tube header. On a cam, places like comp, crane, lunati, isky and the like, have techs that can give you a great range of cams to choose. Just be honest with yourself of what you want out of the engine before you call and ask. Also, know how you are going to be driving it. Be honest with that also in your descriptions.
That leaves your intake. It is too late and I am not foraging for the best way for you to have a better intake system or whether or not it would make a defference. Maybe tomorrow.
January 21, 2007Just Wondering, why do you need 325 HP? Who you trying to beat with that tired 92?
January 21, 2007Do me a favor and don't go bankrupt over a loss. There is always someone who will beat you. 0 to 60, 1/4 mile, top end speed. Winning in one catagory don't neccesarily make you the best there is.
The higher the cam lift, the more special parts you are going to need. As well, that you are not beefing up the important area of the engine block, you are limited in how far you can go, before you lose your engine. A mild cam should do you fine and don't fall into the extra expense of 1.6 or 1.7 rocker ratio. Your valve assembly will be the worse from it. Also, when you do get that 350 horse to the wheels, can your axle assembly handle it? Snap - crackle - pop, you might want to leave to the cereal and not your tranny or rear end. Also, a 350 was never made to exceed 5500 in all reality, although you can bring it up in the 6000 range all depending on the engine and oil flow. Heat aint a good thing. Which means you might want to invest in a high flow oil pump and a larger pan. That also brings into a high flow water pump and a thermostat that can allow the flow. Of course, you will also need to make sure you stop. I see a brake upgrade about to commence. Also, horsepower won't per say make you capable of beating your opponent, you do not want to make your torque suffer. Torque gets you off the line. Intake swap? I couldn't rightly say if it would benefit you or not. Also, you might want to install a double roller timing chain
All the best to you>
