1971 142 Vintage Racer Build: What wouldbe a good cam choice for this Vintage Racer? I'm thinking a VOLVO 'S' cam. If so, would the 'High Performance' springs sold by VP Autoparts support this cam?
Thanks for your advice,
Mark

The S cam is an Isky Z50: 254°@.050", .336" Lobe Lift, approximately 104°LSA.
You need a very well ported head, good springs, pushrod upgrade, stronger rocker pedestal bolts, Twin 45 DCOE's or better, 4-1 headers of the Jere Stahl type.

OMG, brickboard continues to work well.
Also ask this question at Turbobricks.
https://turbobricks.com/index.php?forums/performance-modifications.13/
Yet here is the table that lists redblock camspec info as it was and was a sticky in the Performance and Mod page:
http://web.archive.org/web/20210924225905/https://www.turbobricks.com/resources.php?content=camspec
So I may place this table on the brickboard. Right. Here.
Edit: Gotta scroll down. May not like the table border and cellpadding. Weeeeeeeeeeeeeee!!!!!!
