A machine shop is rebuilding my 1954 truck 235 with the following non-1954 parts:
1. 1954 Corvette cam (a 261 cam)
2. higher compression "848" head - I forget the year
3. The 50-52 Powerglide 235 intake valves (1.94" dia. GM #3835519)
4. Small block exhaust valves, as spec'd below (I think)
Exhaust Valve
Head Diameter: 1.6
Stem Diameter: 11/32
Overall Length: 5.01
Tip Length: 0.25
The engine shop just called me and asked me what intake/exhaust springs I want them to use (car/truck 235 - what year).
Please give me advice - this is out of my little-league level of knowledge/abilities.
