Compression Ratio Vs Pump Gas
Hi allffice
ffice" /><O

I am building a 347 stroker for my truck. I am using ford E7E heads that have larger vales 1.9 int, 1.6 ext. The intake and exhaust has been ported as well on these heads. I am using a HO 5.0 liter block and roller isky towing cam Part#: 371252/257 . I am not going to tow with this vehicle except for the occasional trip once or twice a year. My question is should I us a different piston since the current Kieth Black (KB246) will bring up the compression ratio to 10:1 and I need to pass the dreaded smog test a couple of years from now. Please let me know your recommendations and I look forward to your response.<O></O>
