During the off season I want to put together a new motor for my SDRA dragster that has a little Chevy Gen 3 194" motor currently.
I am looking at a Chevy 250 block pour filled to within 1" of the deck, Bored .125 to 4.00 for 327 forged FT pistons, O deck the block, CR about 11.50-11.75, Clay Smith cam about .550/.550, Small chamber 62cc head with sbc 1.87/1.60 valves, After market 4bl intake with a 600 cfm carb. Will run water in 1" of the block and all of the head. This setup will make 266" and I hope 270-280 HP.
Just a note that we can not run slicks in the SDRA dragsters, only 6" DOT street tires so it helps to keep the bottom end power under control and make lots of top end. Dragster runs a PG with 8.8 Mustang traction lock and 3.77 gears.
What say out there, comments and any past experience with this type motor build? This is a home build motor with cost to be reasonable.
