Thanks for the video Bart. I'm stroking my LS1 to 383 and it is supercharged with a Harrop HTV1900. Currently has the stock cam in it (heads, valve springs, arp bolts, forged internals already but swapping some out). This video has been very helpful. I'm putting in a 224/230 .6 & .61 lift at 112 LSA. I'm not chasing power but low down torque and want to use a standard stall. I also want a little chop and the 112 LSA will give 3 degrees of overlap. Yes, I'll be losing boost but I'm not chasing max hp, just want that low down torque and a little chop. Also concerns about the blower running out of puff high in the rpm range, hence the cam size. Car is a WK Grange. Thanks from Australia!

Dear Lo-Tech. Check out Richard Holdener's channel. He has 100's if not 1000's of dyno runs documented. He did testing on LS cam LSA. He literally tested the exact cam you said would not not pull it's way out of wet paper bag. Guess what? It made the most power. Not just the most peak power, it made the most power everywhere on the curve. Just search LSA cam test. Maybe you might learn something. PS if you want good gas mileage get a KIA.

I designed and built my own cylinder head with rotating tubes where I had to guess the values by myself. I ended up at about 250/250 with a 110 LSA @ 0.050" equivalent. It has about 4-5 inches of vacuum at 700 RPM idle. I was hoping it would work well at 6k+ rpm, but oddly enough the airflow is similar to stock between 4,000-7,000 rpm and a bit better below 4k. If I did it again, I would certainly go to something like 230/230 since it flows better than a poppet valve engine and so I can improve the idle.

4.8/5.3L if you want to keep stock stall and trans go with something around 205-216 intake 210-220 exhaust range. Barts 223/227 cam will need a stall converter, which is perfectly fine. However, on my daily driver and for towing I like the stock stall.

I put a big circle track cam in my car when I was in my teens, it sounded mean, had top end, but all but needed a push start, I had to slip the clutch alot to get it moving, that didn't last long, I don't remember the spec's, but it had over 300° dur, and 106 lsa, it was crap until about 4k and wanted to keep going above 7k, I think it was a 4500-8500 cam, I'd had to put 4.88:1 gears to run that thing it would still been crappy, I had a truck also, I could jerk the doors on a cobra mustang, on the highway, but it didn't have that low down tq, I made a guy with that cobra feel bad, after spending all that money, then get out run by a 5,000 lb truck, I totally respect your knowledge, I'm here because I don't know LS engines, and looking for a decent Street cam for a 4.8 in a s10, with a turbo, and about 10-15 psi, I'd like the boost to give it the top end, and allow the cam to keep the 1500-2500 rpm tq, I'll probably be running a small amount of stall, maybe 500 over stock, so not really a stall converter, with stock 4.3 auto gears, and probably run the v6 converter, now I'm thinking about it, I know the 4L60's aren't the best, but I'm not racing on the strip, maybe the occasional trip down the track, I want the most power I can get, with the best mileage also, 3k at 65 is not me, (anymore) gas is too high, thanks for the video

You don’t choose a cam for an engine, you choose a cam for that engines end use. If you want a perfect cam, you’ll never find one. Every single grind has its own personality. Horsepower , Torque, or somewhere in the middle. You will make gains in some areas and lose in others. Thats the facts.

@tahcogunworks4 жыл бұрын
Hate to correct you, but more overlap does not mean less cylinder pressure for the same duration cams. When you tighten the LC you are advancing the intake lobe which closes the valve sooner. Hence higher psi cranking pressure. Most oval track cars run 104 to 105 LC to help accelerate out of the corner. When I worked at Camonics years ago we found 105 to 106 made the highest peak power but the worst idle. 113 to 116 made less peak power but the best idle. Engines that are FI typically run wider LCs due to idle issues with low vacuum. This is naturally aspirated as turbos and blown cars favor 116 LC to keep from blowing the charge out the exhaust port. Your video is somewhat correct but you fail to talk about other items such as exhaust type, compression ratios, etc. which also factors into this.

I'm so lost trying to figure out a good cam to increase torque and hp with the right parts around a new cam. I plan to use this to tow my toys but I still want more all around power and speed. I have looked at so many configs and found one person who compared several cams in a LQ9. I'm very interested to hear your opinion on a 585 lift 228/230 duration and 112 LSA. Unfortunately I didn't get the list of other parts to make this complete but the curves looked nice. I would like to hear your opinion for a build around this cam and what you would do.
