I have a 3.3 on my Revo, which one of these two would you recommend? I'd like to up grade without making too much modification on the truck.

without much modification the o.s. .21 would be the way to go. but if you dont mind putting steel cvd's throughout the lrp should be ok for a bit but then the tranny will start stripping gears with that kind of torque. Also to put the lrp in you will need a true big block mount from racer66 but if you wanna spend that much on a o.s. i would put a picco .26 i have one in my revo and i love it a little harder to tune but a great motor. if you go with a picco tho you will deff want to run a big block pipe as with really any upgrade bc stock just dont cut it

Thx for all the input CH, I did some research & I think I will go with these one. (O.S. Max 21TM Engine with Revo Manifold) It's suppose to be a drop in with no mods. I'll update, as I go along with the new power plant.

The OS has been a fav or the racers on the Revo for years because of its powerband and its high revving. The Picco is a basher's friend because of its brute power.

The LRP requires a big block mount that is hard to come by. Racer 1966 has started to make them though.

Here's a thread on mine that I just installed:
