A few changes I've got since the 1st build started dropping power.
I should mention the original build was done by someone else not associated with rat bastid, lead 69.
The list of wrongs from what I recall.
Rocker shaft bolts were way to short, bent and snapped both shafts on the 2nd day Dyno tuning.
I measured the head gaskets from the last build.
They were 4.380 bore, my pistons were rubbing the gasket because of core shift I believe, it wasn't all the pistons.
Ring gaps were too small and clearaced themselves.
Rod bearing clearance was too much, I'll have to remeasure but I couldn't get **** for oil pressure.
Dipstick wasn't going down into the oil on the milodon pan I have.
Camshaft was in incorrectly.
Blueprint sheet had my pistons in at 0 deck, what do ya know after decking the pistons were out of the deck +.010
@Rat Bastid does that sum it up.
Oh the bearings were F'd up as well.
The corrections and betterment.
I Sent the pistons in to line to line coating for skirt coating.
I bought 4.410 bore @.051 thickness for a total .041thickness.
New bearings through out. +001 rod bearings.
Plateau honed cylinders.
New gas ported total seal rings.
Nothing wrong with the cam I was running but I was a little rpm limited (that could've been cam timing) but I went a few more degrees duration & a bit more lift.
Got 1.1 points more compression from 11.7 to 12.8:1 by decking my heads.
Opened up the port window on the trickflow 240 heads to Hughes valley pan size and blended it in till it was blended in lol.
Got a tunnel ram from
@MidnightSwinger and am putting a matching billet blp 850 annular booster carb that I was running on trick flow single plane.
I applaud anyone who reads all that, thank you fabo for your support since I've joined
