How much HP do you think my truck has?

[jdiaz]

Yeah the tuck has like 40,0000 on engine and trans. and has gotten everything else mechanical new or new-to-me.

The headers are ****** pro comp headers as I have just found out.

Check out the links below, I know your not in the market for a motor but, this will give you an idea of what is possible from a 350TBI. I was going to get a motor from them for my 95' before I found my 99'. The 95' will be for sale after I get the 99' back from the local Off-Road shop next week. I already have a buyer and a backup buyer waiting in line. The 2-doors are popular vehicles and easily sell if you take care of them and keep them in good shape.

Ur better off either swapping to a vortec motor or atleast vortec heads... Or best results LS 5.3/ 6.0 swap... stock 300 hp a few bolt ons 400 hp isnt crazy...

300HP-400HP at the crankshaft, or how much he'd actually be putting down on the road through RWHP?

I beleive that is crank HP. Depending on the model/year of the 5.3 they range from 290 to 320 to the crank stock. The 6.0 range from 300 to 367 also, depending on the model/year.

Getting HP out of one of these motors is very easy.


To the OP, you might be lucky to have what was available stock. Do an LS swap instead of invest in a new motor.

Yes that's correct at the cam... my 350 is rated 255 hp at the crank but these bad boys struggle to put 180hp down...

From their site: please remember we are one of the few in the country that can dyno test TBI (throttle body injection) engines, and TPI (tune port injection) engines.

BWHAHAHAHAHAHAHAHAHA OK stay away from them, they are obviously smoking crack in between building engines.

Exactly, crank numbers sound great but it is depressing seeing the RWHP numbers after going through the transmission, transfer case and to the rear wheels.
My max RWHP on the dyno was 198 and 253 tq and my truck runs real good.
Of course I haven't dynoed since I installed some more stuff.

I would guess stock numbers to be 180-190

Most everyone that sells something on the internet makes some sort of outrageous claim but, with you being an Elite member and all, I guess I shouldn't disagree.
They are a Top Rated Seller on Ebay with 100% Positive Feedback. Anyone who's familiar with Ebay knows you don't get that kind of rating without doing something right. I've actually spoken to them on the phone and the guy I talked to was very knowledgeable about engines. My guess would be he's not the website designer or the the one creating the ads, But I'm sure you'll find a sophomorish response for that too.
