Way back when I got the Speed Pro normal tensions. I remember them being just over $200 for the set. Youch. LOL.

Probably.

I believe these are them, and if so, wow has the price been reduced over the years.

If you go to the main technical forum you will see my dyno test of various modified 502 parts and throttle bodys recently, testings not done yet, will be posting more info next week after testing a stock throttle body and k/n flame arrestor
Essentially I made 541 hp at 5700/5600 and 568 ft lbs tq from a 502 with 4.470 je flat tops, iron rectangle ports that I spent 4-6 hours porting the casting flash, ridges, bumps and port matching, a 500 efi mercruiser roller cam, fully ported mpi intake with cut down runners, 58 mm TPIS throttle body. Motor made at least 540 ftlbs tq from 3300 to 5300. Bolting a flat plate gen 6 flame arrestor on killed almost 30 hp, comparing the 58 mm TB to a smaller bored out 56 mm throttle body lost 13.5 hp at 5600, I expect a similar drop again going to a stock throttle body. Would still nd up being a fairly expensive upgrade to copy as the hp 500 efi cam wont work with cast iron stock manifolds but some of the info should give you a idea of what will do what, Smitty
