budget 351 Windsor build the block is a late eighties 351 I plan to use the stock crank in stock rods with a forged set of pistons either flat top or a slight dome the heads I have laying around to go on it or elderbrock performer heads that have been gasket matched and bowl blended but they have the 194 160 valves the cam I have laying around for it is a comp 274 nitrous cam plan on running e85 with a carb set up basically what I'm wondering is with the stock rods and start crank is it better to use a flat top piston and spray a little more are use a dome and run a smaller shot and what time kind of times do you think I can get this thing to run it's going to be going in a fully gutted SN 95 with*a*c4 transmission and a 4000 stall
