Thank you for your input I put one on a mazda b2200 and the thing was a tourqe monster but it just wouldn't pull above 4 thousand. Went there that motor twice ported it and polished the intake and some on the head and it just unloved the tourqe even more. Idk how, I heard polishing improves in the higher rpm but it depends I guess
Porting and polishing only really improves hp not torque, the best way I have figured out to improve torque is stroking. So look at this way torque gets you off line or out of a corner quicker but horse power keeps there over the long run. That is why so many high hp motors require you to run in the upper rpm range of the motor all the time, in order to reap any benefit out it. But the down side of stroking it usually takes the motor longer to spool up and has lower upper rpm limit, so its a give and take. And my truck will pull above 6k with the weber I have done it. Now I printed off about six different articles on weber tuning bought the weber manual and used them all "AS A ROUGH GUIDE" and ended up with a way different tuning than they all suggested or hinted at what my should be for my given elevation, which is about 4k.Originally Posted by revvedUpToTheMax

Exactly, I had to jet the weber on the mazda a good 2-3 times before I was satisfied with the engines performance and spark plug color. But thank you for the info, other than a weber and a header what other engine modifications have you added? Cam? I bet a cam in one of these 2.6's would make a hell of a difference in power!
