I am considering Hedman headers, x-pipe, etc for exhaust. 2 1/2 inches sound right?
I am also considering a high performance air intake/filter combo from K&N or Banks.
I have done some research on computer upgrades from companies like Hypertech or Jet. Are the benefits of a chip or programmer worth it?
I have also heard good things about switching to an HEI distributor as far as freed up power and MPG improvements.
When I come back later to do a rebuild, I will invest in camshaft, porting, etc. But I don't need a rebuild right now (only 44,000 miles) so I'm interested in best bang-for-the-buck, bolt-on help.
I'm not looking to race my truck, lol, I just want what towing and efficiency help I can get.
Good places to study are BIG BLOCK FORD'S
or 460 Ford Forum
for ideas........big block fords make outstanding racing engines but they take considerable $$$$$$ doing it.......there is very little you can "bolt on" to get places with the 460........
