86I-ROCZ

I bought my 86 I-roc z28 a few months ago, The carb was tuned majorly wrong, Wiring with the 350 swap was terrible, loose wires and harness's in the engine bay, lights didnt work.

2 days ago i went through all the wiring and cleaned up every single crimp and solder, removed wires from the engine bay, tuned the carb, replaced the heater core(leaked antifreeze everywhere) and even put some Falken tires on it.

The guy i bought it from also said it has RV 202 cams, I can tell by the idle it is cam'd but have no idea if thats actually whats in it.

I have a huge lack of power somewhere, i mean, i have the carb tuned almost perfectly but i am still lacking a lot of power. I put in some nice plugs too. I guess what im trying to get at is, is there anyway to increase the power i put down to the tires without spending thousands?

Also, its a 4 speed automatic with a B&M stage two shift kit. Has a high flow cat with a flowmaster 3" exhaust.

You could hit up craigslist for a cheap used nitrous kit. I know that I seem them locally around here for around 250

Sorry, but thats stupid... This isn't fast and the furious. I want my engine to have the power it should, not slapping some nos in it

Well I'm not going to debate the n20 is for import thing again (pretty sure drag cars used them before the imports did) but it is the easiest and cheapest hp per dollar upgrade. What size carb is on it (make sure if isn't over carbed) have you checked compression to make sure the motor is solid and not losing compression?

You arent going to get much help if that is how you are going to respond.

If it's just a gutless engine, Nitrous is a cheap feasible thing for a quick boost.

If the engine SHOULD have power but it doesn't, check your timing and play with that. You could bump your base timing a couple degrees to see what it does.

Also, what Carb? what intake? Does it have headers? Recently tuned up? Plugs, wires, cap, rotor. You could upgrade the ignition system to a MSD setup.

There is a ton of information on this forum. But you arent giving us much info to what your engine has. And what you want exactly.

i Have high compression flat top pistons, I'm not saying that muscle cars don't use nos, i would do n2o injection though to keep the power continuous. I'm thinking more along the lines of bigger cam(not overly big).

I would not think about nos though before i build the engine/drivetrain.

It has a 750 Weber carb, new plugs, wires, oil, and fuel pump.

Didn't mean to sound like a dick, i just don't like the idea of nos, this is my daily driver. If i was going to drag it yes i would love nos, but for now i'm limiting to cams and such

cams and such...ur broke dude, buy a 98 ford escort for $300 as a daily driver, park ur camaro and actually get it running, obviously sounds like somethings wrong with ur motor bro. just a 350 in an 86 should run GREAT as a daily driver, since you're "not tryna race" with it

86I-ROCZ

Its a perfect daily driver, I do race. There is no reason this engine should not be pushing harder. I have money i just don't care to spend it left and right.

86irocIrock

yea it is a perfect daily driver. when its running right. y'd u post in the engine swap thread anyways?

86I-ROCZ

It runs right everyday, thank you.

What we need to know (and where power lives):

Size of carb, heads (casting numbers are a big help - look under the valve covers), exhaust, intake manifold (brand & model).

Since this has been illegally modified by removing the computer carb (or injection), what distributor it has is also important.

Without that information, we can't help "fix" it.

BTW, RV cams are for RVs. But, unless something is done to improve the other items above, even a cam change probably won't help.

are you even sure its a 350? the "yea its got a 350 in it" lie has been used countless times to pass off a 305. that would explain why it has no power.....

86I-ROCZ

yes im positive its a 350

then we need the casting numbers and such to tell you were the lack of power is comming from.
