An aspect of these engines not given much attention is how strong these engines are. I put a later gen air pump on one of mine with lower compression heads and proper cam grind, 10 years now and its still a very happy engine. Another of mine has near 900 cfm carburation tuned to suit and its been moving the car over 25 years also still a happy little tugger. Gotta say no point on any of that without the good long tube headers (and added welds to the rear spring mounts). I do have front disk brakes on all my thunder buggies. Lots of go needs lots of stop.
An adjustable timing chain.... looking forward to seeing that one. I've been running several high quality built street performance yblocks for a lot of years. They break loose both tires just on engine acceleration on dry pavement, enough for me. 292 blocks with 312 cranks, yup.
Good video. I probably spend way too much time experimenting with various degreeing points and methods but it's interesting to me. I even plot the lift curves in 10 degree increments as well as degree again after assembly with running springs. In the end I try to go by where the cam grinder intended to be checked as well as verifying opening and closing events
Liking to check cams @.200 I sort out my own numbers for I.O and I.C. and then install them where I think they'll run best for the application. Most installations end up advance a couple degrees.
🔔😎🇺🇸 Do you check more than one intake to determine variations ? Or Do you check any exhaust lobe to verify the actual LOBE SEPARATION ANGLE ?? How do YOU determine what LSA to have? Do you ever run test different installed angle to determine which makes best power, or just go with the card ? Thanks for mentioning assymetrical lobes. Shouldnt we be measuring as high as possible ? I like the .200 reasoning, 2/3. 👍 How about timing chain "stretch" ? **** Thanks for the BEST degreeing video that I have ever seen in my many decades.👍👍😎 Pushrod 5.0 HO guy 😁😁 but we've an original rust free '55 272 hardtop.
Great video Geoff!
Keep them coming.

It will a video explaining how to use our 9 way indexable timing set seen on this engine.

@mummertsspecialvinterests2721 yep, if anything I will usually error on the advance side to allow for chain stretch and earlier IVC
Timing chains will stretch 2* in 3,000 miles.@@mummertsspecialvinterests2721
