Are you using the stock motor mount location and using the front accessory drive for the OEM water pump and alternator?

Thanks everyone for the positive comments. The headers are botched to say the least. They are actually cheapo pacesetter 1 3/4 headers for ram pickup with early port heads. So port alignment is not even close for the eagles. Reworked a couple tubes on each side to make them fit. A good set of headers would probably make a noticeable improvement. We don't run any accessories or alternator. Used a truck timing cover and rigged a moroso pump drive to the factory water pump. The mounts are a combination of Schumacher BB perches and street and performance engine mounts.

For the early Dak with a G3 hemi swap, might want to look at the A-body G3 Hemi headers.

I'd be surprised if A body headers will fit. The passenger side upper control arm
Is very close to the head. The frame also angles inward directly behind the engine with the rear lower control arm mount also taking up valuable space. It's just tight.

ric3xrt I appreciate your input. I looked at different headers for hours trying to find some that I thought I could make work. Even some LS and Ford headers. I was willing to cut off the flange and weld on a hemi flange but there didn't seem to be any that looked close. So after all of that, I said heck with it and bought some cheapos and went to hacking. sawzall weld

I'm just wondering what the early 5.7 heads would do with the same cam-combo. Maybe a little port work on the heads too. Sounds so enticing with the parts starting to flow with the Gen lll hemi.

when I mocked up an actual eagle head and early short block and standard head gasket it came out to around 11.5 compression. With the fast burn chambers, double quench pads, EFI, dual spark plugs, plastic intake... I would bet you would be totally fine on premium pump fuel. The only problem you might run into is if your tuner gets too agressive with the timing, these things really don't need much. Heck the apache is 10.9 and you know the factory is going to be very conservative on compression for emmisions reasons (NOX specifically). I think a low buget early 5.7 short block with a 6.1 cam and eagle heads/intake would be a buget motor to be reckoned with.
