hot start problem ls3 hi guys i have just fitted a ls3 stroker motor from scdp it turn over easy and starts and runs very well, sounds great and revs very well, idles well,and turns over with a ratchet on the crank nut. But run the motor for 10-15 minutes and stop it when hot and try to restart it wont turn over (just like a flat battery) which it is not i have tried 3 batterys,re wired it twice, ran extra wires, extra earths,etc etc all make no difference. it is pulling 350-400 amps when hot should be 175 ish ??, the wires dont get hot but the starter does. ive tried 3 std starters all the same, it all pionts to the starter not being up to it but i have ran a few motors like this with no problems, msd etc do a stronger starter , is it for this type of thing ?? comp is 11.4-1 so not that high, any help please people.
Try insulating the starter from the exhaust by using a heat shield or some wrap. I did that with mine and it made a big difference. I also run a power master starter, its clockable and more powerful then a stock type. One other thing you can do is run a #4 or #2 wire to the starter.

If you want to see if its timing related try upluging your coil packs and cranking it while it's hot. If it cranks over normal then you have a timing problem. If not then it's mechanical.
