Nick's Garage dyno's a 318 Stroker.

Just for as an example with my 70 Teen, I messed with the distributor curve which helped quite a bit. I have a LD4B and a 650 AVS2 that can go on. I also have a pair of Speedmaster aluminum heads that can go on as well. I already have them and they were pretty cheap on the Black Friday Sale. Besides, smaller chambers/higher compression, bigger valves, better ports, lighter weight and aluminum for some detonation resistance ain't all bad. Between all that, I have some 60's 340 exhaust manifolds that I can install at any time instead of headers. I need to replace the exhaust system pretty soon because it is still the original that was converted to duals from way back when. It's pretty rusty. For mild street, the 340 manifolds work well if you don't want to mess with headers and many of the exhaust companies have 340 applications with front pipes that hook right up to the manifolds. If the heads go on of course the cam get's upgraded but there's always the decision how far down the rabbit hole to go. Will I need a converter and rear gear change? Probably so if I go too big with a cam. It's all relative. Just like with any other engine build. Now if I just want to pull the Teen and replace it with a stock 360, there's a horsepower and torque increase there without modifying it with speed parts or modifying the drive train to make it work. Lots of things to think about.
