No arguin, just a conversation. Also, gonna hopefully see what one cam can do for this guy. I'm betting not a lot of power, but good enough.

If there is a solid car to work with under that crust, then I think you did alright.

I see. But Hughes seems to still be a little different. Also I the formula works for @.050 lift too, which I checked with the cam specs from Comp Cams. So since Hughes only lists their timings @.050, I did a check and cam up with a duration number that does not fall in between the stated...

I've been doing some reading and stuff. The formula used to get duration "LSA+ (overlap÷2)x2= Duration", is it used by many cam companies? I noticed that the formula calculates with the same duration using the same 110 LSA and overlap as the multple different Comps cams that I checked, like...

Tests would be cool to see on this. 2-4 lbs-ft per degree of LSA does not seem like alot, but I guess in racing every little bit counts.

I plan on purchasing a few books by multiple authors when I get the chance. This will expand my knowledge further and I will have multiple sources to compare and contrast. As for the cam LSA, DV's 128 formula thing kind of goes against what I have learned in the past. Usually too short LSA is...

This is going to be so expensive lol. 450hp with Edelbrock heads and a roller cam conversion, plus going with adjustable rockers if you go with solid roller lifters as suggested. Well, if it makes you happy, go for it and make it look pretty.

Very interesting and very cool.

Continuing, I know that you can buy a used cast iron factory 4 barrel intake manifold for cheap, which was something I was looking for last year, until I picked up my cast iron 2 barrel manifold one day and felt the pain in my back. Yup! That was one of the two main deciding factors that made me...

I forgot to add more stuff. Installed the valve springs at as close to the correct hight I can get. I needed some shims of different thicknesses and was lucky the machine shop had plenty in stock. These springs with the dampers I bought from Hughes to use with their cam as they suggested. I'll...

That car looks great after that wash.

That's alright. Speed Secrets says they will have it soon. Edit: I replied late.

There is nothing there to buy, not much I can do on the site to find the book. Maybe it's because I'm on mobile? I'll check around on the interweb and see if I can find it. Thank you though.

This whole cam selection formula thing from DV has sparked my interest, maybe I might try it for the next engine I do. I want get more engine performance books, maybe I might pick up DV's How to Build Horsepower book.:)

So... once I have the duration I'm assuming that number is the off the seat number? What if the spec of cams to choose from only have the advertised duration at .050 tappet lift?

Ah, I see now. Thank you. I did some math for a low compression 8.6: 1 or so 318 with stock 1.78in valves and would need an LSA of 105 degrees. I'm assuming this is for a ballpark max performance cam and not a normal street use engine that needs high vacuum, or at least for some cases.

Sorry if I sound like a noob, but I'm getting confused because everyone is talking about LSA and DV's 128 formula is for the LCA(lobe centerline angel). I thought, but do correct me, that LSA and LCA are two different things. I thought the LCA is the centerline angle of the lobe timing or...

Alright, part two. My experience with engine performance is mostly for stock factory engines, so I pretty much just fix stuff that is not performing like it normally should in a normal factory daily driver. I've done the some form of easy basic hotroding before to my own junk and some tweaking...

Just wanted to share the slow build of this 318. I know there are plenty of people and articles saying you can build this or that on a low budget, and we all love the idea of a cheap budget engine build. But the truth may be if you are buying a used engine that is not running, you going to find...

That's good enough to make a 3200 lbs car with the right gearing feel peppy kind of quick. If people want something with some pep but don't want to easily break parts, then that is the direction they should go.

I know that some people talk about terrible the stock casting is on these old heads. While porting my 675 heads I have seen how bad the stock ports really are and well... they bad and they ugly. Some ports were casted off center and the casting slag was horrendous.

Update! I just got the headers. I did not take them completely out of the packaging yet. I will inspect everything later.

Is the radiator cap venting? Also, run it with the cap off and see if it becomes a volcano. It may just purge more air out with a little mess and then be fine. Be careful, hot coolant hurts. After that, put the cap back on and see it it gets too hot.

Alrighty, I'll check these places out and see how long of a trip they may be, as I may not be the only one doing the trip.

Ordered the Doug's D453 ceramic coated headers from summit, the amount of money I spent on my total order was a bit painful, but got a little discount, so that's sweet. The guy on the phone was very nice and polite and was also a gearhead. Overall customer service from the them so far is is a 10...

I've been searching, but it's a bit harder to find than I thought. I'm not completely limited on distance, I appreciate anything in the ballpark or alternatives(shipping might be optional... maybe). I was looking to prove some denier/s wrong that have never assembled a complete running engine.

Lol, so true. Remember the tug of war it had with an F150 and the Cybertruck won? It won because the cybertruck was heavier with 4WD and the F150 was 2WD. :steering:

That's my kind of deal! Hopefully somebody can do something with it, because it's really not that bad, or at least looks not that bad to me.

Freakin' sweet! :thumbsup:

2 plug wires in the incorrect firing order can make your engine sound like it has a rod knock(forgot which ones). If messed with the plug wires recently and you have a mild knock, check your firing order. If you did not mess with it and it just started to happen, then oof.
