a B cam? WAG 225 hp

225

I1m not sure but l would guess about 280. I`ll keep an eye on this one cus l am curious

Coming from the factory with 240 horse, 225 seems a bit low, do not ya think? Increasing the cylinder volume has surely increased the power a bit, as well as the cam. This is one of those questions that will be hard to answer, because so many variables r at play here. If u r truly curious, u should do a dyno test. This will be the only way u will get an accurate reading. Anything else is just speculation. l know from experience with my own 89, l had just under 300 to the wheels. l had 1.72 roller rockers, 306 block, e303 cam, underdrive pulleys, & a manual rack. Hope this helps.

If all you did was the cam and had the block bored, and nothing else (no head work, stock exhaust, etc.) You're looking at around 240ish HP and bad judgment for going through the work of tearing down the engine yet not at the minimum throwing on a set of GT-40 heads or Trick-Flow intake.

235/ maybe 240, the bigger cylinders and cam are not doin much without a good set of flowing heads and intake. Plus the b cam is a single pattern cam and is very mild. Put some afr 164 heads and a holley systemax2 intake on her along with full exhaust, bigger throttlebody, maf, 24lb injectors, 4.10 gears, underdrive pullies, and a cai, and you might get over 300 horses, and have a pretty torquey street car. you really want a lot of torque for a street car not high hp numbers
