I was going to get a 440 kit but i think i will be better of with either the 416 or the 426 kit. i know you don't have to resleve these kits all you got to do is bore. i want to be able to run on 93 octan or pumped gas so a 10:1 or a 10:8 is probably the way to go but how much fast really would a 426 be to a 416? ups and downs? but i might just go all out in either the 416 or the 426 which i probably will anyway and just get a 13:1 and run race gas.

I have a 426 kit in mine. I love it. shows very good power increase and everything. The only thing with a 416 is that when it goes bottums up you are able to go to a 426 without resleaving it. I would go ahead do a 426 though. I have had mine in for more than a year now and it still runs strong.

I agree with Natertot. I also hav e a 426, used to have a 440. I haver my 426 dialed in better, and its faster than my 440 was. But in fairness, if I had the 440 dialed as well, it would have been faster, I think. This 426 revs quick! I have a custom lightened piston running 11:1 on 50/50 mix.

i've been researching the very same thing as u, i've found that if ur on a budget, it will be cheaper to get a 416 kit. the 426 costs more for service. also, the 416 and 426 rev faster than the 440. if u get the kit, it is recommended to get new exhaust, a new carb, new cams, and and u will need a new gasket kit. i've been in touch with a guy from C&D racing, and he's been givin me this info. good luck!

Sandman. IMO the oil tanks are not worth the money. Its not oil capicity that is the problem its cooling. 4 Stroke Tech (Mickey Dunlap) has a extra oil cooler. Its real nice, drops head temp by quite a bit, drops cool oil right on the cam. Its real nice. It adds 1/2 quart of oil, and gets it cool, all for less than $150.00
