Re: 1/2 tooth off timing belt options

That sounds pretty simple. Some have suggested I need to time the stock cams/crank if I'm using the adjustable wheels. You would seem to disagree. In the meantime, rotating the intake cam counter-clockwise makes the intake valve open later which might tend to reduce power but improve fuel economy an...

Re: Hey Brad, have you seen this? Small bore Holley Sniper

I would love to try this but I'd have to take the really cool Weber carb bumper sticker off my Spider.

Those venturi sizes (35mm+) seem pretty big for an 1800.

Re: 1/2 tooth off timing belt options

When Ray Mortensen of Performance Apex in Renton, WA rebuilt the engine in the mid-90s, he built a head with Delta cams (I don't recall the details anymore) with extended valve stems so regular shims would work, and higher compression pistons. Even with a single carb, there was so much valve overlap...

1/2 tooth off timing belt options

I have a 1756cc engine with high compression pistons that ultimately required a thicker head gasket. As a result, my cam timing marks don't exactly line up when the crank is at its mark. It's 'a half tooth off'. The number of teeth between the cams would not have changed from stock. The car runs fin...

Re: Need information on an odd combination

It sounds to me like the previous owner put together an engine combination based on whatever they could find, cheap. If it was done 25 years ago before the internet was big thing, one can imagine how it might have been harder to find the 'right things'. The only thing that made me choke up (because ...

fixing slow wipers - 2019 edition

Lubricated all the moving parts in the arms. Added a 14 gauge ground wire between the wiper motor mount and the cowl on which all the wiper bits are mounted. Sheet metal screws hold the cowl in multiple places, ensuring that one has a good ground from the motor to the body. I also installed a new mo...

Re: Adapting 5 wire 128 motor to the Spider (6 wire)

So the 128 motor connector has five wires in the same housing as the six wires in the Spider 6 wire motor. The motors on the outside are the same size/shape, no differences in mounting. The colors of the 128 wires and where they are in the housing are the same as the colors of the wires in the 124 m...
