Title: somewhere the article from 1976 HVW's on Dean Kirsten's 1679 was posted. Post by: Jim Ratto on December 03, 2009, 01:39:07 am Sorry, used search and couldn't find it. It was the article of the build up on his 88 x 69 motor, with custom Engle cam, etc.
Dean, any impressions you want to share about that motor in the blue '67, I'd enjoy reading. thanks Jim Title: Re: somewhere the article from 1976 HVW's on Dean Kirsten's 1679 was posted. Post by: deano on December 03, 2009, 03:47:43 am Jim, looking back at that engine build up, the biggest problem I had to over-come was getting those (early) Total Seal rings to come in. If I had the do-over, I would have kept the stock KS rings and that engine would have made a lot more power on F&A's dyno than it did. We had a lot of ring leakdown that never improved. The cam I ran was a special grind that Ron Fleming had Engle do, which was a 120/125 dual-pattern. They only made two of them. The intake had a W120 grind, and the exhaust had a W125 grind, to even out the flow differences (ratio) on the two ports. Worked okay on the 1700cc, but really worked better on the 1900cc (same engine with a 78mm SPG), and finally, on a 2074 (same with 92s). The other 120/125 cam went into a 82x88 biral cylinder engine F&A built for a midget engine. Made great power.

As a footnote to your post Dean, I used a couple of FAT's custom Engle 100/110 cams in our desert rails.....worked perfect. No surprise since FATmotors dominated short and long course off road racing at the time......but that's a saga on to itself.

I love that feature ;D

Ha Ha as I scrolled down and saw the article then the shot of the engine I said out loud to myself "awesome" Cool bring back Jim and thanks Fabian you got something old school brewing in that head of yours Jim?

That was a very cool motor.

Title: Re: somewhere the article from 1976 HVW's on Dean Kirsten's 1679 was posted. Post by: deano on December 04, 2009, 15:26:16 pm Yes, Mike Dawson and I did a lot of cool things together. He was over at Brea Motor Parts back then, before he went to work at Auto Craft in La Habra. His dad, Jim was a super guy as well.
Title: Re: somewhere the article from 1976 HVW's on Dean Kirsten's 1679 was posted. Post by: DKK Ted on December 04, 2009, 16:57:42 pm I worked with Mike at Auto-Craft, he worked on heads there, was a machinist there myself. I believe he went on to work doing his own thing by the river. He had this bad ass yellow Baja bug that was lowered a bit in front. He let me drive it to check out the way his engine ran cause I was deciding on what to build for myself. Have you heard from Mike, how is he doing, if ya did??

Title: Re: somewhere the article from 1976 HVW's on Dean Kirsten's 1679 was posted. Post by: Jim Ratto on December 04, 2009, 18:25:41 pm Dean, thanks for sharing memories of that engine. The 1679 setup has lng been one of my favorites, ran a nice one in my Bus, though not tuned anywhere near yours. Closer was Bryan Wenzel's 14 sec. version in his stock '65 Bug
How was powerband with the 120/125 Engle? Do recall the carb setup, vents and jets? Interesting, before we built Sheep his 1914/K8/Mary Pauter heads/IDAs/Crown 6lb, we were building him a 1679 with W125, Jeff D 40 x37 "D" ports, 48IDAs, etc. Still want to build it one of these days, maybe a second heart for my car. Title: Re: somewhere the article from 1976 HVW's on Dean Kirsten's 1679 was posted. Post by: deano on December 04, 2009, 23:31:07 pm From what I recall, that combo was a little weak on torque and I really did not like driving it all that much. A 78mm stroke went into that same engine almost immediately. Jetting? I think I ran a 145 main 165 airs, 37mm venturis, 65 idles, 32 degrees timing. I ran the crap out of that 1900cc for years, and finally, replaced the skatey-eights with ninety-screws for a 2074mm. I loved the way that engine ran and I never had one bit of problems, even at 11.0:1 compression. Many, many years later, the guy who bought it finally dropped one of those goofy 9mm/914 exhaust valves and did a lot of damage. Steve Tims fixed the head, and I think he found someone to fix the SPG roller crank. That engine is still kicking around at Glamis somewhere.
