I’ve got a 402 with the following, keep in mind I’m just bumping up a little as this is my daily in a 70 k20 pick up.

1-pistons look like 5-10cc dome?
2-heads are 3999241’s open chamber 113cc combustion chamber large ovals (I heard these were very good heads, they actually look bigger in runner size than my 781’s I sold last year.
3-Edelbrock 2162 cam
218 228 @.050
.500 lift
114 LSA
(Again....I know, very mild but I heard same specs for 69 l88 ZL1 cam which is cool if true.)
4-Edelbrock performer rpm Airgap intake
5-no carb decided yet but temporarily will use adapter for Quadra jet until I get a carb.

again I know this is very mild, everything seems so tame compared to my 496 build which you can see in some of my previous threads. Thanks guys.

Here are some pics of engine

Pulling the 402 out of my parts truck.

It would be between 325 and 375. Good luck
