Well the good news is it didn't blow up. The bad news the numbers were very disappointing 415hp and 465tq. I was embarrassed needless to say. The owner of the shop has a 390 Fairlane. and it did 50 more hp with 60 cu.in less and basically the same set up. Af was 13:1 he said it was lean, I thought anything under 14:1 was OK. I thought I knew what I was doing but its clear that I don't. I was expecting at least 500 hp. The car sounds mean just but it makes a little more hp than my Suburban. Any suggestions would be appreciated. I was planning on going to Maryland at the end of the month but now I have my doubts.



So here's the specs
428 block .040 over Eagle 4.25 stroke crank, Scat rods, Cp 10.5:1 pistons, Barrys cnc ported Ed heads intake 310cfm exhaust 178cfm I think. custom Comp cam solid flat tappet very simialar to a 294, ported Streetmaster, Msd ignition, Hooker 1 3/4, flowmaster 50s 2 1/2 out the back, Holley Hp 850, fidenza aluminum flywheel,TKO-600, 389 rear. I think that covers it.



Suggestions welcome somewhere there is 100 plus hp hiding

This may sound stupid but have you checked your exhaust system for stray chickens, owls and other unwanted guests. I had a perfectly good mower run like crap because a mudwasp liked the smell of the muffler and decided to move in.
