1915cc.

rear tire size and trans gearing will also dictate how well you do in traffic, but i'm sure others that have more experience running that size motor will be able to answer your other questions for you.

I have a 1914 in my sandrail with a stock tranny. I beat the snot out of it Just ask Hans :P I've blown one tranny and that was an old 6 volt. Just don't go crazy starting out.

Post by: James Buchan on April 12, 2007, 06:09:14 AM: When I first installed my 1914 I ran with a stock tranny for a few months, even saw some track time with it. As long as you don't shock the shit outta it on the line you'll be fine for cruising around.

couple more things, with this 1915 what kind of raockers do you suggest? as well as push rods and lifters? and cam?

i am thinking reasonable though, not dirt cheap but not crazy.

Post by: Chris on April 22, 2007, 07:22:36 PM: Most of the engine builder types are really busy this time of year, but a 1914 will not have any trouble keeping up with traffic, and you can pretty much use any rockers you want, maybe a set of 1:1.25's will do the trick for you, not too wild, not too mild.

What cam were you going to run?

Post by: vanBoven on April 22, 2007, 08:08:46 PM: that is what i was wondering :D would i use stock push rods and lifters too then?
Title: Engine Stuf
Post by: Chris on April 22, 2007, 08:32:48 PM: im no expert but the lifters would depend on what cam you run, and as far as I know you would have to run different pushrods, again this is all dependent on what cam/lifter/rocker combo you use

My motor is a 1914 with 1:1.4 rockers and a web 98b cam with web lifters, I had K-roc do my lifter geometry for me as he has the experience and tools for setting it up. Of course my motor was setup to get power out of it not so much for daily driving.
