Why? The optispark is crap, go ahead and put a good ignition in it.

This is incorrect. A locking differential is like a detroit locker. They "lock" while going in a straight line. When you go around a corner the inner tire slows down by the differential turning that tire slower using a ratcheting type mechanism. If they stay at the same speed then it usually...

Well, if you reread what I wrote, it's new heads E-Tec 200's with ceramic coating, Stealth Ram intake, thin head gaskets (steel shim) and maybe rocker arms. So, yes it will get me at least 50 maybe more my Dyno Sim does not include a stealth ram intake so I had to improvise. Nothing special...

Since it was starting to have this problem prior to the shop visit I would lean toward a failing fuel pump. Have them do a pressure and volume test on it, NOT JUST PRESSURE!

The problem started after the work on the carb, so, that is the problem. I would guess the secondaries are not opening. If it was the power valve it wouldn't run at idle.

You have to convert from optispark to a distributor. The optispark is a sorry ignition, so converting to a standard distributor will allow a larger choice of parts and a MUCH hotter spark.

Oh, DO NOT start that engine!

Something is HOSED! You shouldn't have to spin it more than a couple of minutes, depends on drill speed. And three rockers total on both sides, that's messed up. Need more info on what you did to help.

There is NO replacement for displacement, the bigger the better. If you can afford the gas. My 89 bird gets 21 mpg on highway at 75-80 mph, so build it smart. :wtf:

Howdy y'all, Recently dicided to build an SS and so here I am learning what I can to plan the build. My current play toy is a 1989 Pontiac Firebired GTA Trans Am. But I gave it to my son, so I need a new toy. :? Here's it's specs, same as the signature. 1989 Pontiac Firebird NIGHTHAWK...

Thanks for all the replies guys. I'll keep everyone posted on how it goes. Just in the planning stages now. I gave my 89 Nighthawk to my son, so I decided to build a Monte Carlo SS to replace it. I put up a photo album of the NIGHTHAWK if y'all are interested in it. Have raced it...

New lifters should be soaked in oil and then pumped. Take a pushrod and pump the lifter about 4 times to get it full of oil, just soaking may not do it, whereas pumping will. You want to make sure that the valve you are adjusting is resting on the base circle of the cam prior to...

I got everything for the rear suspension, great parts, very well made. However their subframe connectors were total crap. They require you to weld then the entire way to the floor. Get BMR.

Oh, one more thing, if you find the timing starts acting up then recheck TDC or 0 degrees on the ballancer. IF it is no longer pointed at 0, then the elastomer on your harmonic balancer is failing and you need a new harmonic balancer. If you can't see the markings on your balancer to start...

I'm a FNG and I have a question. Does anybody make a kit to put an LS motor into a G-Body, 85-88 Monte Carlo SS? I cannot find one. If no, does anyone make ANY parts to do this swap? You can just buy a kit to do this on an F-Body. :D Thanks!

Go to the auto parts store and get some timing tape. Disconnect the battery. Pull the number one plug out of the motor. Take an old plug and bust out the ceramic and center electrode. Put a long bolt through it, it cannot move, thread it, JB weld it, mighty putty it or something but make...

I just joined this forum as I've decided to build a companion to my Nighthawk after I gave it to my son. Do you guys bicker like this on all the links? Get a grip! The LS1 is the better motor, all the way around except for ease of installation. I want to drop a 500 - 600 hp LS motor from...

I understand you have the motor, but putting in a small block chevy will make you happier unless you spend some bucks on that Poncho mill. The rope rear main seal is a JOKE, the conversion kit is expensive. The heads are terrible, flow, port design, combustion chamber, they make decent boat...

It really doesn't matter. The rings rotate as the engine operates, so they do not stay where you put them. Just make sure you don't have all the gaps lined up when you install your pistons.
