Which is better? (mega/feigao)

[speed demon]

Yes they came oem with shaft rockers but the MP heads I got have the pushrod holes moved over for a bigger port window and the only company besides T&D that would make a set with the offset I needed was jesel. They are way over kill so are the heads but I wanted the ability to go to a solid roller cam(550lbs open) and more cubes but at the time the R3 blocks are way too much and the XR blocks weren't out yet. The car gets me were I need to go for now. Kinda taking a break from it.

I know what you mean about driveshafts. When I first put the 340 in after taking a mild 360 out I blew the driveshaft taking out some thrust washers in the trans a busting something in the new coan converter. 2 weeks and 1500 later I had it going again. That was my first trans I have ever fully done and I still have nightmares about it but I have over 20K miles on it and it works perfectly.

Oh since this is a rc forum....what fan would work with the MM? Does the MM have a port to hookup a fan or do I have to get the power from my receiver?
