Quick update to those following the retro 3.2 project.
Talked with Dema Elgin for a while today. Will be adding 10 - 15 intake duration over stock 244 with more overlap. He feels no need to re-profile the exhausts. Looking conservatively for about 15 - 20 hp increase across the band (4v characteristic) at the rear wheels and more torque across the band. If all goes well, that will put me at 245 - 250 rwhp, which is at my target of 299 - 305 hp at the flywheel after losses. May get a tad more with some more ignition advance. Pretty damn good on street gas and stock 9.2:1 compression.
Will require welding, straightening and heat treating - all told looking right at $1K. It's a lot, but the sound and the engine's personality are really waking up with the Webers. Not sure of the effect of the Larini Euro stepped headers and silencer, but they are mainly for sound. Any hp increase will be a bonus.
Should get the cams back 1 March. Will install the Norwood Mallory distributor conversion at the same time. Am keeping the carbs jetted a bit rich in anticipation as I am going to have to change all of it anyway.
Dang, this is fun and I am learning a lot. I guess when I move to Texas this summer my new interests will center around air conditioning performance....
