what would be best BIG BLOCK engine to use with Revo

[Bartek]

Hi,I would like to swap my traxxas engine for a BIG BLOCK engine in few months but I'm not sure what would be an best engine to use with Revo and what would I need to change it.

I've been wanting one of these https://www.rcnitrotalk.com/forum/showthread.php?t=66608 . I believe they bolt right up to the factory motor mount if you're running the 3.3. Theres also a few others depending on how much you want to spend and how many mods you want to do to make one fit.

A high rev'ing 21 would work well with the revo. Considering the revo's weight, pretty much any big block has more than enough torque to flip you on your head all the time. So, get one with ridiculous top end power and RPM's.

Like one of these:

Hit up the 1/8 buggy section and see what you can find that people like for really good mid-top end power and high RPM's.

Olds, I was thinking the same thing with the OS Worlds Engine.I have seen it for around $400.00 also.The OS is suppose to be proven to work with the Traxxas Big Block Kit.I want one.I think the big blocks are much more user friendly and reliable.I know you have to change to a 1/8 clutch ect though so mabey a little more up front but in the end its probably the way to go.

I didn't even notice your question about what you would need to change it.

To use a true big block, you will need a conversion kit/mount, header and exhaust. Depending on the kit, you may be required to use a bump start vs pull or roto.

Unless you just want a drop in engine. Then your list is more limited. RB makes a few, Picco makes a few and OS now makes one. I'm sure there are others, but not many.

Even with a drop in engine, they would perform far better with a better pipe than stock (on the 2.5R revo). The resonator pipe is pretty good for a rear exhaust pipe.

I have chosen to get an Picco P2 26

in my opinion the picco .26 max is a really good upgrade against the 2.5 and 3.3

it's one hella of an engine...

Might I suggest the O.S .21 V-spec.
They've even designed one that just drops into the Revo with out any modifications to the mount. Also it is designed to except the Traxxas pull start and easy start.

great engine but picco sims to be cheaper.

Ya, picco is a little cheaper! I've heard a lot of good things about the V-spec and that's what I'm planning to put in my truck later. I've heard good thing's about picco as well. I typically don't like to recommend something to some one if I haven't used it or heard about it to much and that's why I didn't recommend the picco, because I don't know to much about it. I pretty sure that it's a good engine.
