Hi does anyone know where to find a performance cam for the 235?
beside clifford?
thanks

isky used to made cams for the 235.The one I had a bunch of years ago was called the E2.

Wow thanks guys.
I just got the tri carb intake for my six.
lets see if it fits c40 1962.
Hope its not waay to much carb?
anyone here have experience with a tri-carb setup?

It works best with both end carbs blocked off. Use them as eye candy and run on one carb like the engine was designed to do.

tri-power can be difficult to tune for the street.I had it on a 235 for about 3 yrs.I usually disconnected front and back for driving around town.Reconnecting when challenged.The gas milage was awful.Jerry's idea of blocking off two carbs is a good one.I'll think on this,,and see what I can remember

I agree with Jerry and BC52. I'm only running duals on mine, and they were a pain to get tuned right, 3 would be a nightmare, and not worth the trouble for a street driven truck.
I notice you mention that your truck is a C40, perhaps you might consider swapping in a 261 from a C60 if you're looking for more power.

yeah the 235 is original with 45000 miles.
I want it to be useable but very different.
My machinist he specializes in racing motors has over 50 years under his belt..
Says pita!! but he can do with custom jets to keep reasonable fuel economy..
so let's see what happens??

progressive linkage would be good for the street.Most of your driving on the centre carb,all three open at full throttle,if it is adjustable you can have three carbs open at the same time.I've heard that on tri-power some people have disabled the idle curcuits on #1 and #3,but way back I didn't know about this,so it wasn't done on mine.It could get rich in traffic.I wish I could remember the jetting,but sorry I can't. The cool factor of tri-power on an inline can't be beat

Ive heard the 261 cam is a slight bit bigger and works well in the 235. Have yet to try this myself. But I hear thats what they did with the blue flame six for more power.

What type of performance do you expect and also how many RPM's are you building the engine to get it's maximum performance at? If you are looking for a little better this will get that fore you. If you want to move up a bit and get into above average performance (acceleration and sustained power) then consider the cam and kit Patrick's offers as a complete kit. There are others out there too. But make sure you consider rear end ratio, transmission type and ratio's of each gear if it a manual type. And finally, how much do you want to spend? Buying a cam isn't simple if you look at all of the factors to be considered. Normbc9

There was thread a few months ago about the 261/Corvette Six camshaft. The camshaft discussion starts near the bottom of page 1 of 2.

I have the "3/4" cam from Patricks and frankly I don't like it. Idles too rough and doesn't add much over a stock cam or a 261 grind.

If the idle and tip-in are bad after a cam install, you may improve it by:
1. increase the initial spark advance 5° or so, and deduct this from the mechanical curve.
2. is the throttle disc still in the correct position (.040" of transfer hole exposed), or did you have to jack it up?

Hi thanks for the advice.. I'm thinking the 261 grind later.. Just want to maximize available power without going to crazy.. the machinist is reserved for later after the bodywork is done..and it runs pretty good with the split exhaust and single cab right now..am thinking of possibly using a twin carb setup instead of the tri setup I picked up.. I appear to have firewall issues with the tri carb setup;-)

howard cams can grind you just about anything you want for these engines.
