I may have got the technicallies wrong. What I meant was there is an easier way. I would look for the Post on another Forum, but I don't remember what I was searching for when I stumbled across it. |

Re: Tune-port install
TPI's make good truck motors because they produce a decent amount of torque. The L98 in my vette put down close to 300 ft lbs at the wheels when it was stock. If you're going to upgrade beyond the TPI, I would just skip the LTX stuff and straight to the LS series. A 6.0L from a late model truck would make an awesome truck motor. Plus, the aftermarket is packed with parts for the gen III/IV motors.
If you're looking to add some HP's to the TPI start with the intake. The stock one is very restrictive. There are some cheap alternatives though. For starters, check out www.lt1intake.com Or, check out the stealth ram and mini-ram intakes. |
Re: Tune-port install
Sweet sounds like a cool car (56 Belair)
Yes definitely skip the LTX and go to LSX |
Re: Tune-port install
If you have an LTI use the manifold off that on the TPI setup it will solve the poor flow problems at higher rpms and won't cost anything (or pick up an extra LT manifold at your local pick a part for $25). Just need to bore a hole for the dizzy and get a remote thermostat housing modify the bolt holes and your good to go.

Re: Tune-port install
The TPI that i'm installing first doesn't need to be a power house...my dad just wants something that is unique and is dependable, with some power.

That's all he is looking for...now once I finish his and feel comfortable with installing the system, I'll start buying the parts to do mine. And it'll be a bit more extreme

Re: Tune-port install
Grab a harness/computer from a JY. Should be cheap. If your wanting more power, that might be tough without a tear-down (different pistons/heads). Different runners might help a little though! You can coax 325hp out of a 305, but it might get pricey. But hey, not everyone and their brother will have one! I also agree that 3rd gen camaro site is very useful. Good luck!

Re: Tune-port install
I have had this motor running for close 20 years in my 71. It has never let me down except for fuel pumps but that has been solved with the baffeled tank.
I installed this motor back in 89 and Street & Performance was the only company doing this stuff at the time. I got a V-6 Ferrio computer with S&P wiring harness. My factory harness is all there nothing has been removed. All the gauges are as were form factory. The S&P harness was all plug and play with a Hot,ground and fuel relay wire and the rest plug to the motor. I wish there would have been all these choices back when I was doing mine but hey it was fun. http://216.77.188.54/coDataImages/p/...1/DSC01187.JPG http://216.77.188.54/coDataImages/p/...8/DSC01556.JPG |

what valve covers are those? |
Re: Tune-port install
The valve covers on that engine are the original titanium colored covers from the 90 Vette that it came out of. They had some stains on them from the brake fluid that spilled onto them when it rolled over, so I sprayed them with a silver color until it came time to do something else. I have a set of chrome covers in storage for it.
The factory GM exhaust components for the cars and trucks should fit the heads. That side is basically the same as a standard GM 350. |
Re: Tune-port install
thanks
i am really really bad for guessing hp what would you guess be for a stock 98 350 vortec with a tune port out out of a 88 firebird that has been ported? |
Re: Tune-port install
If you do some engine updates and the computer is bumped up for performance, as well as bigger injectors. you could get to 325 or 350 HP easily. However, the stock engine, with a standard TPI you will get the 265 HP range. Example, this vortec motor from PACE Perf. with a multiport injection and a vortec motor.
