I will voice 2V since I owned one for about 10+ years. The engine is very easy to work on and trickflow already uncorked the power from 2V back in 09. I think its settled that H/C/I 2V will out shine a stock displacement H/C/I 302. Is it more expensive yes, is it worth it on NPI long block HELL YES. Doubling the power out put is always worth it in my book. I would of done years ago but we all have other priorities. I'm not knocking the 302 because I helped work on them but each engine has its pros and cons. Once you understand 2V modular and what needs to be improved on you can surprise a lot of people and crush a lot egos. This is what I am planning to do when I do a F1-A 8 rib conversion. All these engines need is heavy duty rotating assembly and some forced induction. I think thats way better than punching out a 302 or buying a aftermarket block to hold the power but to each it owns.
