[trazzaldazzel]

currently getting into a pontiac 400 build and I'm new to the pontiac motors, I would appreciate any and all advice as there are a lot of knowledgeable people that have a lot more experience than I do. im looking to build more than one of these motors, a friend wants one for his 71 cutlass, i have plans to put one in my 87 pontiac grand prix and give it the proper pontiac power it deserves... specs on current engine:

1974 400 ci cast # 481988 YT 220 factory rating
cylinder bore is 4.121". (.030"+ bore is 4.151
.030 overbore to make 406 ci
2 bolt mains
deck height 0.030 -
3.75-inch (95 mm) stroke
factory rods, rod length is 6.625

Keith Black/KB Pistons 1526-030 - Silv-O-Lite Cast Pistons

so with that being said, im looking for recommendations for head/cam combinations that will work well together, I'm looking for 350-400 hp. looking at 72cc heads with 2.11/1.77's, for example #13's, 16,62,48 and so on... looking for any advice, mild-medium cam that would work well with this. any input appreciated so dont hesitate! thanks
