Re: head work or bottom end?

Headwork! Just know the limitations of the bottom end. No sense in building a top end to destroy the bottom end. Typically, the bottom end can handle 9000rpm with the weak link being the oil pump. My current engine is running 8500rpm limiter with a totally stock bottom( yeah it bounces a lot and I ...

Re: head work or bottom end?

With the 272 cams I'd kick the limit to 8500. IF you were to go the other way, block, I'd say put the funds into a 7A block and build a 7AGE. Not as rev happy but the torque increase is worth it. If you were to go this direction a light flywheel and rods will help with the "sluggishness" ...

Ideally you would know how far you can adjust before the valves hit the pistons so with that in mind... Generally, once armed with the knowledge as above the cam timing would be adjusted whilst the engine is on a dyno. What would I do ? Advance the inlet first (cam timing wheel held still, turn the...

Re: 4age with 272 cams and carbs

As I understand it, the chokes are used to match the carbs to the airflow of the engine. More airflow means you use a bigger choke. Longer cams allow the engine to suck in more air once they start working, so going to a larger choke (or removing the chokes if you are already close to the maximum si...

You sure your accelerator pump is working? sounds like a flat spot from instant flooring. Again I would double check that you have spark and that it isn't blowing out/losing spark at that rpm/load. Idle jets shouldn't have anything to do that rpm. What's your whole set up? Pictures would be cool as...

Re: 4age with 272 cams and carbs

The easiest way to tell if the mixer is rich at 3000 rpm. Does it run better when it is cold, Vs up to temp. If so, then you have a rich mixer. Dave w7 it seems to run the same through out the temperature range. just started up/160/180 seems to do it at the same rpm. heres where I think its a littl...

Re: 4age with 272 cams and carbs

The usual effect of installing longer duration cams is to move peak torque/power higher up the engines rpm range. This results in some loss of VE down low and an increase in VE up high. I'm not familiar with the range of mixture adjustments available in the DCOE carbs, but the engine may be over-fu...

smoke comes from dipstick tube and from valve cover breather If this is obvious smoke and only after a short time of running it would suggest a piston and/or piston ring problem.
