No problem Bill, using good ARP head bolts, they should hold the heads in place. Now head gaskets might be another issue. Frank we may have to take some of that good Indiana corn and brew up some special racing fuel if prices keep going up. Like I said earlier, we will print all the engine specs after the dyno results. I have a potential date with Ted on 16 May to pick the engine up, and then we will all know what it will do. I will say, this engine is very similar to Ted's roadster engine.

I have heads with combustion chambers smaller than those domes, make sure you put the recording close to the pipes when you fire it up and post it, I love the cackle of high compression engines.

glenn, i do believe thats the prettiest set of pistons i have ever seen peeping out the top of a block. congrats on being a second time grandpa too. its great!

OK, WE ARE MAKING SMOKE!! I talked to Ted today, he had made 5 or 6 pulls and after some set backs with a water leak,  was over 400 hp @ 6200 and he is still tuning on it! I'll be heading out there Sunday so I can be setting in his driveway bright and early Monday morning.

I can sense your excitement Glenn.. It will be nice to apply Y-Block Torque to pavement. Hope you get it finished for Columbus

Yes RB, getting excited. Good Lord willing and the creek don't rise, we will be in Columbus.

Ted emailed me a dyno sheet, but dumbass me can't figure out how to convert it from a pdf file to a format that can be posted to the forum, so for now I'll just give the top numbers.

H/P 415.4 @ 6000

TQ 400.8 @ 4700

He was still working with it friday so these numbers may change a little. He was finding that carb spacers were making a huge difference, I'll let him talk about that later. He was having a problem getting the idle down to where he wanted it, but some of that may be the Isky 505 T cam, it was at 1200 rpm and he though that it should be around 1000rpm.

This engine is very basic, so I am well pleased with these numbers.

292 block, 312 crank = 337 ci

mild ported posted G heads (stock dia valves)

Wiseco forged pistons (13 to 1 cr)

Isky 505T cam (Dove rockers)

Mummert intake (stock out of the box)

Eaton modified 750 vac sec Holley carb (830 cfm)

Here’s the dyno sheet for Glen’s 337” Y.  This should make the Falcon a real bird of prey.
