A pump is for displacement. A whistler is for compression ratio.

I have a katech whistler an use it alot at the dyno. Some circle tracks will have rules that mandate a maximum compression ratio. If you have one near you maybe you can get the tech guy to check your motor for you.

Let me preface this by saying I don't have any drag race experience. So these these thoughts are coming from someone not in their lane. The op stated that the car puts the front tires in the air on launch. When the front tires are in the air, my thought is at this time they have little...

Do you have any pictures of the rear suspension?

Thank you for the clarification.

Thank you for the detailed response. Was he able to match a cap up or did you have to line bore or hone?

Do I understand correctly, did he replace the rear main cap?

Take a look at the 440 source stock replacement rods and compare to the cost of having your stock rods magnafluxed and reconditioned with new rod bolts.

I don't know. Even if it could be welded, the cast iron cylinder head welding wizard around here has retired. And even if he was still welding and could weld it, it might not be cost effective. The builder and customer will have to work that out.

I agree for the most part. There are some applications where it makes sense to cut the seat. An example is the EQ magnum head. EDIT: ( I don’t know if this applies to the China EQ's) It has a very short installed spring height. Sometimes offset keepers/ retainers won't get you where you want to...

If I count the 602 crate motors we see more failures with solid flat tappets as a percentage. To be fair most of the solid flat tappet cams we see are fairly agressive circle track profiles. No rollers allowed except in the 604 crates. They are broke in on breakin oil with the correct procedure...

Did you mean to say convex? Or high in the middle? I hope so.

Wouldn't roller lifters need shorter pushrods? And longer valves need longer pushrods? In general.

Also I 'm right handed and tend to scroll with my right thumb on the right side of the screen where the red x is. Too bad they couldn't move those options to the center of the screen and or add an "are you sure" step to it. Or just get rid of it. If you disagree you can say so in a post along...

Tell who?

Nice work Rusty. You probably saved that engine from getting damaged.

Take it to a shop that can braze or weld cast iron. If I was doing the repair I would choose brazing. After that I would use a stud if possible. Might want to have the rest of the block checked first in case you find something else wrong with the block that makes it unusable. Good luck with your...

Which book is that in? Thank you.

Does anybody have the measurments for the 440 8 bolt crank register diameter and the bolt circle diameter and spacing? I need to make an adapter for the dyno. Thank you.

Yup, fat fingered a big red X. Sorry about that.

Not my channel but it is my head. He had a request on a previous Q and A video for a review on the trick flow 240. So I sent him mine so he could review it. Thought that someone might find it interesting.

Thanks everyone for the replies. Lots of good info to unpack.

This isn't a specific recommendation for a set of wires that will fit your combination. Hopefully someone will have that for you. But if they don't here is a caution and suggestion. I just did a wire re-do on a customers 440 based stroker in a b-body. He had some wires laying against tubes...

I watched the video link you provided. While he did point out the short comings of the head in the end he said it would be " leaps and bounds ahead of a stock casting". For what that's worth.

Different applications have different priorities. The methods used to provide timing for engines in different applications vary based on those priorities and the comprises that have to be made. In some applications it will make sense to have a locked distributor with no mechanical or vacuum...

So maybe not as useful but not necessarily useless. Agree?

If you really want to know how manifold and ported vacuum work try what I did. Get 2 vacuum gauges a couple of vacuum t's and some extra vacuum hoses. connect one guage to manifold vacuum and one to ported vacuum. You can route the gauges through the door if it doesn't pinch the hoses shut. Put...

I agree with what you said however I disagree with the statement that "ported vacuum is useless" ported vacuum functions the same as manifold vacuum once the throttle blades are opened. Which is most of the time you are driving your car. So if manifold vacuum is beneficial at times when the...
