How many head shims are needed in this engine(all stock) for 50-60% nitro usage. Seal kit appears to come with two(different in color) shims. If using both does orientation matter in stack up?
Tired of seeing this sit around and collect dust. I have a new in box CMB .67 Greenhead and Cmb muffled pipe 67/80 to sell. I will also throw in a new collet and used header for $550 plus shipping.
Capacity will double but not amperage. Two 50C batteries in parallel will be 50C. Voltage also remains the same in parallel. Series nets double the voltage with the same capacity. Available C rating never changes, only capacity or voltage depending on wiring configuration.
Have personally serviced GM's with well over 500k miles with only major repairs being worn injectors with high fuel return rates or the ocasional one that is hung open. Have one still in service with 640k miles on it and it still pulls 5th wheel travel campers coast to coast. PM's as Mikey...
