349 CI on the cheap

In the 344 engine which is a std. bore 318 instead of .030. I used a stock cheater cam and a set of 318 heads. The heads have .120 in stock uncut form from the deck to the chamber roof at the quench area. I used the 1.78 intake valves and the 1.60 exh. valves. This way I have high compression and a good quench as the piston comes out of the block .075 and I used a .020 MP head gasket so the piston sticks up out of the hole .055. Then I machined the top of the piston as shown eariler, so that the top of the piston would go into the open part of the chamber and make my quench .038 after machining the heads to match. This way I can use the open style heads from eariler years. This gives me close to 15:1 but a cyl. pressure of only 150 @ cranking, because of the bleed off of the cams overlap. According to my program it should make 638 HP @ 6,500 rpms and 542 ft. lbs @ 4,500 rpms. And it sounds like it too.

The heads flow 215 @ .400 lift and the cam opens to .473 int. and .494 on the exh. CL is 106 straight up. The 318 heads also flow 198 @ .300 with the small valves. The exh. peak flow is 207 @ .600 lift but this is just for reference as the cam doesn't open this far. I'm looking for solid 6 sec. passes in the 1/8 Friday night. But once again will see as anything can happen.

Oh the cam has 275/272 @ .050 duration.
