SLO-030 Posted March 23, 2009 Report Posted March 23, 2009 Get the 3khead shaved and reconed. If you just want shits and giggles, stick a dished piston 5k head on the sucker. compression would be thru the roof and i wouldnt expect the engine to last to long. Quote
TWF#14 Posted March 23, 2009 Author Report Posted March 23, 2009 how long do u recon the 5k head would last as its being used for speedwing doing about 7000 rpm? Quote
