I've been chasing a problem with my engine stalling in gear once it gets hot ever since I got it running, and I'm hoping someone here can point me in the right direction to possibly fix this thing.
Engine is a 408 small block, 670cfm holley carb with a 1/2" phenolic spacer. Trans is a 727 that was converted to run with a lock-up converter at the advice/decision of the guy that built my trans. 3.23 rear gear. Fuel pump is a Carter electric and I'm running it through a regulator and getting 5.5psi consistantly at the carb. Engine RPM in neutral is about 1100-1200, in gear is 800-900.
When it stalled today it was at the end of a 12ish mile drive to the parts store, right when I was about to turn onto my street, and it stalled again when I got in my driveway. Once in the driveway I started it in neutral and as soon as I put it in drive it died. Let it sit off for about a minute, fired it up, put it in gear and it idled in gear for about 30 seconds before it died. Water temp got up to 220 since I had to wait for a train and didn't drop much once I got rolling again (no shroud at this time, waiting on some welding resources and will have a custom one on next weekend).
I thought I had fixed this problem with the fuel pressure regulator since before I put it on I was getting 8-9psi at the carb and flooding the carb. Apparently that wasn't the only issue. I'm thinking it's the lockup converter not disengaging and really hoping that that's not the problem. Is there any way I can test that without having to drop the trans and pull it out? Anyone else experience this issue and have any advice at all that they can share?
I'd really like to be able to drive more than 12 miles without this thing stalling.
Thanks.
