without swaping heads or getting head work done your looking at approximatly 400 hp depending on the cam and intake and carb match.
set of headers and a dual 2.5" exhaust with some flowmaster mufflers and a edelbrock 4bbl. intake with a 600CFM 4 bbl. carb. a better way is to change out the 8-1 pistons for a higher compresion ratio 9-1 10-1 11-1 12-1 ect call ross racing pistons they got em or wiseco
375 sound right?
32-34 degrees
it depends on how big the pistons are the bigger the pistons the bigger the torque and smaller the horsepower.
simple! 305 vortec heads, 10 to 1 pistons, high lift roller cam, free flowing intake, 600 CFM holly carb, A good set of headers and an HEI distributerShould get you 300 horse.
That would be called a 355 cubic inch engine. As far as horsepower no one would know untill it was put on a dyno machine.
There isn't a formula for equating horsepower to displacement. That'll be determined by the injectors, the displacement, stroke, and compression of the pistons, and other factors.
Need alot more information IE what intake? carberated tbi? what pistons? rotating assembly? but jus very ruff estimate should be around 280-300 flywheel hp well the motor is a late 70`s motor carburetad slightly better pistons than factory dual plain elderbrock intake with long tube headers.
A .030 bore alone wouldn't add enough horse power to even feel. Now, add flat top pistons, a good cam, headers, maybe a decent set of heads and carb you'd see improvement. But if you added that to a stock bore 305 you'd see the same results.
Hi, only one size of pistons will fit - need to match the bore diameter - unless you want to rebore the engine to increase capacity. However, there may be a stroker kit available for your particular model.
You cannot convert cc to horsepower. cc is a measurement of the size of the engine. In other words cc is the bore x stroke x number of pistons. A 420 cc engine could have 15 h.p., 30 h.p, or any other amount.Displacement doesn't correspond to horsepower. Lot of other factors involved.
cc (cubic centimeter) is a unit of volume, of the piston or pistons. It can't be directly converted to a unit of power (kW or horsepower), although it is certainly one of the factors that makes an engine more powerful (other things being equal, more cc means more horsepower).
