it was a shameless plea to borrow your jigs, i didnt want to buy some stock maniflods to make the jigs and end up w 2 sets of stockers.
i posted too hastily and shouldnt have asked. i apologize.
the weapons charge? untaxed modified barrels, as in really short and equipped with silencers for ak's and ar's. once again, folks, always pay your appropriate taxes and fees to the govt.
the manifolds,
we started out considering the method you are pursuing, much preferring the aesthetics of the first tube and eliminating the second or third runners.
we were concerned about keeping the pressures as equal as possible and thought perhaps when under boost and full rpms that there would be a pressure differential between the front cylinders and the other 4 due to the different runner length to the actual log.
when we had water cooled log manifolds on our old 60's 70's lake boats the runners to the log were always equal, the last being a hardin marine 455 olds 390hp,. old days i know, but all i have for experience. so we opted to amputate the odd runner in favor of the a match, right - wrong? no clue.
i am sure someone on the board will know a lot more than i do and illuminate me on fluid and thermal dynamics.
btw have you looked around the last runner of the passender side log where its welded inside? mine had some sharp jagged edges and we are thinking they will heat up and glow causing grief. later we wondered if they were for anti-reversion or just rough welding practices. i think rough welding.
