Andy,I’m considering is removing this extra joint and going straight into the block, by opening up the current feed holes and tapping the block for an pipe adapter. It’s a lot of extra work, for not a lot of gain, so that’s why I’m still un-decided.
Looks like the lifter in picture number 3 may have a burr or two on the sides! :lipsrsealed:The cam timing has been now checked and found to be within 1 degree of the manufacturer’s recommendation – good enough for me. Stainless steel mesh has been added to the valley drains, which is held in place with epoxy resin.
All piston/rods fitted, although originally I managed to build up 3 rods with the pistons the wrong way round (the rods have a larger chamfer on one side of the big end to match the fillet radius on the crank) and the Spirol-Lock circlips are a right pain to remove.
The heads are Edelbrock Performer RPM with the 1.9” inlet and 1.62 exhaust valves. Even though it says ‘performance straight from the box’ I pulled a couple of random valves to check seats etc and I must say the quality is excellent, especially fro the price. The valve stems are necked and the valves seats are nicely blended into the ports
Even with the raised crown pistons fitted, the piston/valve clearance was checked with modelling clay and there is plenty of clearance. The only annoying part is that the standard steel rockers foul on the larger spring retainer (although in fairness it does say this may be an issue in the small print of the cyl head instructions). I could grind them back, but I don’t like the idea of weakening them. A set of roller rockers is now on the shopping list, as well as a new set of push rods as hardened ones are required to work with the guide plates.
I’m now waiting for the front cover to come back from machining, before the sump can be fitted.
Regards
Andy
I figured it must have been something like that - or - you had one HECKUVA high lift lobe there!!!Hi Randy,
You got me all worried then about the on the tappet :laugh:. I justed needed a longer extension on the lifter, so I screwed a suitable tap into an old lifter body
