stroker for a splitty

Greetings. If I was to build a 78 x 88 or a 78 x 90.5 for our 67 bus should I consider a lightened flywheel or keep the stock weight. We will retain the stock gearing and redux boxes until the research is done for the optimum transaxle and gearing for our application. Thanks

I'd keep it stock.... May keep the redux boxes happier, unless you snap the clutch!

a 78x88 single port with big valves and port work is AWESOME for a bus... I did one with a web 218/119 cam for a Splitty and it was amazing.

That cam was one that we originally had made up for single port offroad race engines- it loves single port heads!

Keep the heavy flywheel on the bus as you need the lugging power not fast rpm changes. If you get big valve heads, keep the ex valve size stock for low end torque and open up the vale pocket around the intake or your new heads will breath worse then stock. Also Low compression is a must. www.vwhelp.com

Thanks for the tips from you both. I was leaning toward DP heads, mild cam, 8:1, 40 Webers, 1 1/2 exhaust. Built for a low rpm application. If I get to 5k , it'd be a cold day in hell. As a side note to J. Raby, I haven't ruled out T-4 power. Got a 2.0 core setting on the bench. I just feel the need to increase my T-1 experience. The real T-4 power will be for our 78 westy. Thanks again

I didn't know you could readily do 78X88, but that would be nice. I've thought of 74X88 for my bus, but probably won't ever happen. I've got a Berg 78X90.5 and it did pretty well in the bus. I'm going to stick with SP heads on busses from now on. Also 88s for T1 engine. It just runs so much cooler. Running a bus in high altitude desert makes me appreciate this. 2L t1 was nice. The 2L tIV was much nicer. I took it off for heat, but you could really feel the torque going over a pass compared to the T1 2L. Now I have a stock 1600 in it and it amazes me that it does as well as it does with big tires and 3.88. You definitely know when you are going uphill though! If you have the $$ and want the power, go tIV. If you can get by with a little less power go SP with 88 cylinders on T1. DP heads run hotter on a stock motor and on a bigger motor it's worse. I'm not saying your DP motor is going to explode, but busses are hard on T1 motors and anything you can do to cool them is good in my opinion. Adding 3.88 trans makes the engine run hotter too. I've got a little 1679 SP in my 58 panel that I drove to California and back and it just wouldn't get hot even going across the desert. Less power, less heat, more dependable. Just my experience so far.

Very good info. Thanks for the reply and thanks for reading. I learn something new everyday. Am I to think that with SP heads, we are limited to stock induction with one carb?

I have ran Kadrons and 34 ICTs with single port heads...

Busses like single port engines!

A single port is the only Type I engine that I have found good for cruising, long life and fuel economy.... I've even built a 2332 with single port heads- pure animal!

I've heard some good things about CB's dual solexes too depending on how big of an engine you go with.

jake, what kinda power did that 2332 make with the SP heads?

very interested idea.
i build many daily driver single port engine but never with more than 1800cc.
what is your 2332cc combo: heads/CR/cam/carb vents?
I have several parts to build a torquey 2276cc bus engine with a 3200/3500 max torque RPM and i must choose cylinder heads and cam for this combo.
What do you think about
37x33mm reworked single port heads
web 110/163 cam or with a 9:1 CR (93 unleaded here)
and a center mount 40DRLA/34vents
1 1/2" heater box with a CB performance bus dual T-bird.

thanks for all your advice.
