ET Report Card on the Speedmaster Heads
Why do you have your 340 out?
Originally pulled it out thinking it had spun a bearing. But it had not the hillbilly that built the motor did not put the correct washer on the front of the cam and so the fuel pump eccentric was wobbling against the inside of the front timing chain cover making a squealing noise.
Try to make this short. Tore down, I discovered that all 8 of the valve seats were cracked once again the hillbilly had put some 205 or 206 valves in the heads with 11/32 valve stems and blah blah blah anyway all of the seats were cracked so I'm waiting on my new ported 915 heads from Moparofficial and then I will put the 340 Back Together, with it's .060 over 10.5 cr TRW pistons and 508 purple stripe cam and 8 in Turbo action converter.
It is after all A Streetcar.
Right now it has a completely stock 360 with stock heads and stock cam in front of a manual shift 727 and stock converter and 4.88 spool.
