engine swap questions

[fluffytx1]

I have a 68 GMC, I am finally retiring the old 351 v-6 (spun a main bearing) and going to a small block 350. I am have rebuilt the TH400 tranny and have ran into some snags. HELP!!!! 1) I have looked at some other trucks with a 350 and the stands that mount the engine are different than the ones in my truck. Do I need to swap? If so where can I find them? LMC does not carry them, and there are none of these in the salvage yards. Is there any years that will work? 2) II dont want to go back with factory exhaust manifolds. What headers will work? 3) That 351 was really heavy and I compared my front coil springs to a friends and mine appear to be larger than his. Should I change them? Has anyone ever done this swap before? If so is there any other problems I should prepare for?


Thanks Scott
