I just bought my first ls1 and am wanting to get more power out of it, the car is a 98 z28 with hooker long tube headers, Texas speed x pipe, slp lid, yank ss 3600 stall on built tranny, 342 gears, 160 thermostat walboro 255 fuel pump and its been tuned.
I have a little extra cash but am wanting to get the most power for the money I can spend. so my questions are what will give me the most bang for my buck? witch cams choice would be good? ported stock throttle body vs 85mm?
ls6 intake? ported heads? or what combination of those things.
also will the stall converter make my dyno numbers less accurate?
ive herd of people blocking off the coolent lines to the throttle body. what advantages does this give?
any other ideas for cheep/ easy power?
thanks for any help ahead of time!

Will any of the upgrades I talked about earlier recquire bigger injectors? Or will my stock ones work? If it is a good price I may go pick it up soon. Will I need to buy anything else to make it work or is it a direct swap for my ls1 intake? He said its ported to run a 85mm throttle body. Will I see any gains if I use my stock one?

Would I be better off with a cam and eather ls6 heads or ported ls1 heads? Or a cam and that ls6 Intake? I read somewhere that the intake is only good for 15 hp or so. And I think I could get more then that out of swapping heads. But what's better? Ported ls1 heads or stock ls6 heads?

when you do a cam swap its smart to replace the valve springs, pushrods and timing chain, with that being said you are going to spend more then $500. I bought everything used and spent about $700 and I installed everything myself so there was no labor cost and plus your going to need a tune after the cam install. Also heads are going to cost you more then $500, your best bet would be to pick up a ls6 intake or save a little more for a cam swap and a tune.

if i went with the ls6 intake would i need a tune to see the added hp? and would i need a bigger then stock throttle body to get the added hp?

what cam is in the car currently ?your stock injectors will be good enough unless you get ported heads.a ported TB has the entry smoothed out,no ridges.if you get a ls6 intake ,carefully remove some of the ribs on the bottom of the intake .this allows use of the stock ls1 coolant lines.measure the TB opening be fore you buy a TB.a ls6 uses a 3 bolt TB.

I was told the underdrive pulpy is a bad Idea. Somthing about the Stock one has a rubber section to reduce vibrations on your crank and the aftermarket one does not so the vibrations are bad for bearings. Any thoughts on if this is true or not?

i heard the same thing, but u have to spend like 400 bucks if you wanted a underdrive harmonic balancer. Listen if you can find a ls6 intake and its in good shape buy it, ask if the throttle body is included. (most likley not) they can handle up over 500hp.I have a 92mm fast intake ported with a nick williams 90mm tb and produced 15hp give or take with out a tune, with a tune in the mid 20hp range. Also the a simple flow solution if you dont have a aftermarket air lid is to take your stock one with plyers and break off the damn luvers on the inside of the air lid and have a round sander for a drill and smooth it down good for 5 to 7hp. not bad for a freebe
