305 chev engine starting problem

I have a jasper engine 50.000 miles in my 1967 nova ll.

The engine started draging after shutting it down and starting it back up?

I replace the batt. & 2 starters because the engine drags after warming up.

I had it in the shop and they made a heat shield for the starter but nothing
helps?

Once it at normal operating temp. and I turn it off it drags so much you
wouldn't think it would crank but it does?

Elec windows drag too!

Now I thinking it taiming problem but what would temp have to do with
timing?

I know it's something simple but it's got me!

Thanks

You could easily be describing a bad connection in one of the main power
cables. The sneaky one is the battery to engine block connection and
the engine to body one.

It sounds like your timing is too far advanced. I don't know why
temperature matters but I know it does. Try retarding the timing a
little bit. Good luck

Hey, right on gxsr! He asked what temp had to do with timing--shoulda
asked if both temp AND timing could make engine harder to start: yes!
Advanced timing makes engine fire too early and "kick back" on piston's
movement = hard to start, or "starter drag". Heat swells pistons--remember
that piston "slap", a noise due to excessive piston-to-cylinder walls
clearance? It is quieter when hot and is due to piston's expanding &
reducing this clearance after it heats. This same swelling could cause
"starter drag". HTH, s

That's right, the easy way to check this is to disable the ignition system
and see iff it still cranks hard.

An engine with too tight of a piston to cylinder clearance will have far
worse problems than slow cranking when hot.
