Siamese Porting
I have Siamese porting on plenum and SLP runner (upper portin)
would it be wise to siamese lower portion of runners and base?
Basically stock L98

Re: Siamese Porting
My guess is you may not get many responses since there are a number of threads and a ton of information about siamesing the base instantly available by using "Search".
I will say I don't particularly care for the mod, but I can see it being useful as a stop-gap or interim mod on a highly modified or large cubic inch engine until you can get another intake. In any other situations,, my personal opinion is siamesing the base takes away the only good thing the TPI has going for it,,, the midrange "tuned" boost. Once you siamese the base, you end up with the worst flowing single plane intake on the planet - definitely not something I'd want on a basically stock L98.
