I have an original hood tach that I want to cut into the hood of a 69 400. I have no idea where to locate a template. Hopfully someone here can help.

thanks,

Bob

I was just reading about the hood tach myself.... HERE is some info that should help. You may need to scroll down the page a little ways to find the part about "tach placement"

There is some dimension on the first generation registry.

I've got the template that came with mine, can scan and send it to you on email if needed.

Nash,

I'd love the template, what I have is an original, I'm not sure if it has the same cut-out as the aftermarket. Anyone know for sure?

Thanks,

Bob

Does anyone know if the repro hood tachs have a switch to go either 6 cyl or 8 cyl? Been thinking of buying one for the 6 cyl car.

230Sprint6, I've never seen a hood tach for your car, minimal redline is 5100 I think. However, that does not mean a hood tach wouldn't work on your car. Your ignition is sending the signal, which is then converted internally. Don't know what reading you'd get?? Mighty interesting idea though!

Bob25, I don't know the answer to that either, though I do know the underside of the hood limits where you can actually mount it. There should be a triangular/rectangular cut-out(weight-reduction) point beginning 4-5 inches from the rear lip of the hood (in front of drivers area, as seen from the underside of the hood).
That area is the base spot for where the tach will bolt into. This allows the mount bolts to go through the hood, yet not go below the lower hood base and into the engine compartment, the bolt studs should be flush and not stick out (or IN, in this case). This allows the hood heat blanket to snuggly fit with no wierd bulges due to extended bolt studs poking in. Also allows for wiring harness to be run without creating bulges in blanket.
I looked at the template I have and it is generic for the GTO and Firebird. Bottom line is you may move it a little this way and that to get the bolts right, just make sure it is looking dead into your face from the drivers seat.
I suppose others with 400 hoods can tell you different, but thats what I have. Mine IS a Repro hood.

on the 6 cyl hood tach. yes.
6500 RPM redline for 230 66-67
5500 RPM redline for 250 68-69
...is what i have read on the OHC forum. there are a few posts about them.

here is one thread: web page

The face or redline could be fixed to meet the 6500 rpm. I'm just mostly curious to see what rpm it runs at whilst screaming in low at 60 mph and I like the look as opposed to defacing my interior with an aftermarket tac. I opened up my cheap tac on my Barracuda for some reason (didn't care about defacing the Mopar) see the tac on the dash and it had a switch to go 4, 6 or 8 cyl. Thought it would make it so much easier if the repros would be similar.

Year One sells them for the 6.

Sweet Cuda Gerry!

I knew I had this some where... but I have so many links saved... it get's overwhelming! Time to clean house and organize again! Lol...
