Can a 2 stroke engine start hot or cold?

This isn’t a hot 4 stroke we’re are talking about here, 2 stroke engines are very easy to start hot or cold, and hard starting is a sign that something is not right in your engine. All that kicking or pulling is just wearing out your starter and probably your leg or arm in the process. This is all assuming that you have already checked the basics.

How can I tell if my HEI distributor is bad?

When checking for 12 volts, do so while you are cranking the engine. If the battery voltage drops below 10.5 volts while cranking, you probably have a bad battery. This low voltage could be insufficient to get the distributor to fire. Use a volt meter to test the hot wire while a buddy cranks the engine over.

What’s the difference between the pre 86 350 and post 86 block?

Pre 86, Post 86, Vortec. Use the correct intake for each and have no problems. There’s a ton of different stuff. Ive got an 87 350 out of a Suburban in my truck. These engines were a big POS. They use centerbolt valve covers, and if you use stock heads, the temp sender sizes are different.

How to calculate timing on a 383 Stroker?

Measure the circumference of the balancer and divide by ten; cut a piece of masking tape that long (which is 36*) and place it on the balancer, clockwise with the end butted against the timing index line. When the bottom (most clockwise) end of the tape aligns with the “0” mark on the timing tab, you’re at 36* BTDC. divide by 36 that gives 10 degs.

What’s the difference between pre 86 and post 86 carb intakes?

They use centerbolt valve covers, and if you use stock heads, the temp sender sizes are different. To use a carb intake, you have to buy the special post 86 pre Vortec intake, or find a pre 86 intake that has enough meat around the 4 center bolts to hog them out enough to get the bolts in. Even then they wont go in straight.
