I have an 88 Iroc with a 5.7 and a 5 speed. It was converted by the previous owner. I'm wondering which starter is correct as I've got a major issue with starting it when the car is hot. Thanks for any help.

 

for a manual tranny you want a 153 tooth starter.

also, check your timing, if it is took far advanced, the starter will have a real hard time starting it. it's often called "heat soak" but there is no such phenomenon.

 

Those heat transfer rocket scientists at work who use that term all the time are going to be disappointed to hear that.

 

...i meant in starters on automobiles.

i know that "heat soak" really does exist

i suppose i just said that wrong. people think the problem is that the starter is too hot and that is the reason the engine is hard to start.

the real problem is because the engine(not starter) is still hot, the air/fuel mixture will light off easier, and if timing is too advanced, and you don't have a super duper gear reduction aftermarket starter, the cylinder will fire the piston back downward before it reached TDC(and the crank moved past 90*), turning the engine backwards because the starter didn't have the power to keep the crank turning the right direction.

i know you were just being sarcastic , but a lot people think heat sheilds are the answer to all their problems

either way, check your timing, set it too the factory setting, if car still has trouble starting, its probably your starter, the right one is 153 tooth.

 

The stock starter is pretty weenie; it has a real problem turning over a large motor with high DCR when hot.

The LT1 starter is a direct bolt-up; or, you could get an aftermarket mini-starter. I have the CVR one. I put it on when I had a 400 in the car (T-5 car) because I got so tired of it being so hard to startr when hot. It was unbelievably different from the lame stock POS. It spins the 400 at least twice as fast as the stock one could spin a 305.

I wouldn't waste time on heat shields and solenoids and all that crap; just go straight to the root of the problem, which is an inadequate starter, and deal with it. You'll be REAL glad you did.
