383 cam selection mistake??

[rkohlman2013]

Im just going to run it. I will have some 906 heads and a TM6 intake for sale soon. Ordered a dual plane edelbrock and picked up a set of 5090 Edlebrock heads since it was tore down anyways. Cam that is in it seemed to pull hard. Cant really identify it but did find a Melling 111819 number which is basically the same with a little more duration than the P4452783 purple shaft. Have some adustable harland sharp rockers and 8.250 push rods in the mail coming soon. I apprecaite all the information and help with 383 cam info.

Yeah i measured them at 80 thou in the hole. Using summit compression calculator it comes out to 8.8:1 with the .027 head gasket thickness with 75cc heads with the 4.31 bore x 3.375 stroke….. still cant find any info on the cam numbers…..

Yep, 0.080" in the hole.

Did you measure the 915 chambers? Unless you did some cutting and/or larger and thicker margin SS valves, They are usually closer to 78-80 cc.
