Re: Isky, Piper and other performance camshafts for the 2.5 V8

Here's a thought , -- I'd be reluctant to load up the cam drive gear anymore than needed , so the idea of an external pump ( belt driven )just to feed the cam might not be a bad Idea. Not nearly as complex as a dry sump setup and could still be feed from the sump . The pump capacity would be calcula...

Re: Isky, Piper and other performance camshafts for the 2.5 V8

I agree TJ. The only reason i've hung in there with the org. radiused followers is that my research will benefit others who aren't as open to modifying the org. So my own profiles are to that end.

Re: Head Gasket fitting

The decking of the block to bring "bonny" pistons up to level ( 50 #) along with 50 # off the head gets the push-rod scraping the push-rod hole at the block surface . This then needs relieving a tad to clear. Shimming the rocker pedestals has the detrimental effect of moving the sweep on the valve h...

Re: Isky, Piper and other performance camshafts for the 2.5 V8

The cams wear due to regrinding through or near through the case hardening. The solution is to rebuild the profile the regrind or use a billet that has been hardened . The cam/follower should have a hardness difference to reduce wear. If the base circle is reduced much to give more lift the system i...

Re: coil resistance .SP

Howdy Mike , How're things down there ? As well as the resistor type application the electronic systems can also run .5 ohm coils . Follow Keith Humps tribulations in Dart Talk of late. I haven't tested his current (4th) coil as yet but asking for guidance across the counter at Repco is not recommen...

Re: coil resistance .SP

Have tested four coils , old /new , A Lucas branded new reads 1.7 ohms, Lucas stamped 1964 - 3.5 ohms , Bosch gt 40 (2) 3.5, Crane for electronic pickup (2) 0.6 ohms. So there's a great variance between brand and application. Have recently brought the third SP home from the paintshop and almost comp...

Re: coil resistance .SP

Good one , thanks boss .
PS., now have the 2.8 short block in my workshop. Will blueprint the heads to the block over the break.
( pistons stand proud of the face so the chambers may need dressing to give a 30 though interface across all cylinders . ) Cheers to all --- have a safe one.
