Type 4 Store 2270, Type 4 Store 2270 Options

[lexatola]

I'm getting close to pulling the trigger on the 2270 engine kit from the Type 4 store. I'm curious if anyone knows what the difference between the kit and the Raby 2270 SR. I see they each have different HP specs. Do we think this is an actual difference or just a difference in written spec? Same cam? Same Heads? Curious if this kit can make better HP than 140? Headers? Other tested and ordained cam?

I'd appreciate any input based on experience,

Best,

Alex

Unless you are stroking it stick with the stock rods and crank
Cam I like the WEB 163/86b
You have to do CR and shims, no way around that.

Absolutely. Split duration, originally recommended to me by John of Aircoled.net for my very last ever aircooled engine, a 2270, and it was good. Needs serious heads and exhaust, but you knew that already.

Rods could be Carrillo, pauter or redone rabbit rods
44/48 mm webers, take your pick, or djet.

Actually while they're offset grinding the main journals for stroke DPR can also resize the rod journals to T1 size. Then you can choose from any of the hundreds of T1 I or H-beam rods in whatever length you like. Lightweight, cheaper than T4 from Carillo or Pauter, and more than strong enough.
