What should I do???

Ok well I've decided I am going to probably rebuild my current 350:CRY: until I was browsing the classifieds today.:HMMM:

I found a 396 for sale :3dSMILE: for around $1500 he said he would sell the motor for


or he has a 400 block for about $100 :whacked: that I could slowly build and swap in for my 350.:D

I do not want to lose power, :o wouldn't mind gaining some :rolleyes: but my motor will need to be rebuilt soon if anything. All I know about my current 350 is what the PO told me and was this---350 .030 over,4 bolt main, pop-up high compression pistons ( I think 11:1), Torque Cam, Z28 valve springs, High volume oil pump, Heads have been milled, Factory Corvette intake, 780 cfm carb., 3500 stahl converter. 3 angle valve job.

Should I stick with the 350, build up the 400 or try for the 396, what do you guys think???:confused:

The 350 has 4 bolt mains ...............why not use it ?
Have you determined the current problem with it ,with tests..........?
