There are many good inexpensive combs available it just depends on what you are trying to accomplish. In Liberty Dan
I'm not sure what you mean by 'trying to accomplish' this engine would be a street strip engine on pump gas, 11:1 comp, I suppose I'm trying to find out the differences between scat,eagle, probe,callies etc 4340 cranks/rods, have only ever used a scat crank/rod before that worked out ok! What to use what to stay away from.
The cast steel Scat/Eagle cranks work good for what you are trying to do. I would go with some type of 4340 rod and a Ross or Probe forged piston if money is real tight we have used one of the Hypereutectic pistons (KB) up into the 475 hp range. In Liberty Dan
I think mainly Dan meant, how much power are you wanting to make, will it be drag race only, road race, street only, nitrous/boost, etc...
There are the cheaper $1000 kits that will hold up about as well as a stock 351 late model block. Say around 600-700 fwhp at most. Then there are the forged kits out there that can handle 1000 horsepower plus with supporting parts.
Is this going in a 75 and newer block, or in a 69-74 block? The older blocks are stronger and would make it beneficial to go with all 4340 stuff so you can handle more power in the future.
I have all Eagle 4340 crank/h-beam rods with Ross forged flat tops on my combo. No problems so far with around 650 n/a and 750-800 (maybe) on nitrous. I plan to make some more n/a and hit it with 300 this year.
