Yes Jeff. The '70 intake is the pancake type, but the older tall intake can be used and It looks like the new tall 359 GM Perf Parts intake is optional. I just had to look and it looks like there is quite the mix of ex valve sizes. 69/375 iron =1.72, 69 401 Alum = 1.84, 70 402/w401 alum & iron = 1.88. The head CC is all over the place too. Both 69 & 70 w/401 alum are @ 103.3 CC. the 69 iron 396 is @ 104.9 and the 70 iron 402 is @ 106.9. The pistons have a diffrent height. 69/396 is .361 at 40.05 cc,,, 70/402 is .344 at 39.53 cc
So much for using a 396 +.060 claimed as a 402 + .030. The cubic inches would pass, but it looks like you wouldn't make it through the barn with quite a few other parts. Sorry for being so technical tonight, but I just had to know. Sad deal for Luke too.
