Hi all,
Things are calming down and I am back to working on the Alpine and I need a lift and duration recommendation for a cam. This is what I have got.
Block: 1592cc bored .040 over
Pistons: Hepolite flat tops .o4o over
Con rods: These were made for Alpine Racing and bring the piston almost to the top of the block.
Crank: stock
Valves: Stock dimensions
Valve Springs: Isky Duels 625 626
Rockers: Harland Roller Rockers 1.5/1
Head: port matched with Vissard Modifications
Carbs: Two DCOE 40 Webers with a Redline intake
Exhaust: Custom header
Distributor: Pertrox electronic with Bosch high output coil
I have had sort of a Goldilocks moment with cams. I tried a stock cam first. Way too cold. An Isky race cam 430 lift 286 duration WAY to hot. I have a Cal Cams cam in it now which I have no idea what the lift and duration are but I think it is comparable to a KB grind. It is barely adequate but I am not getting the most out of this engine. I am going to get a cam cut.
So, what do you think? Your thoughts would be greatly appreciated.
