Wel i dont100 percent agree as the bowl around valve is larger then standard port thers proven hp from it but i think its worth it and its had bowl work .
Il look into changin to 3k carbs if I'm runin outa puf or c if i can use the the venturis or maybe save for some su if u thinjm they would be a big benefit. I got a head4 it now with bout 33mm ports to go wid me 32 ml runners and I'm going to polish the combustin chamber and exaust port
these were of a hq sedan these shocks are pretty much new had no black gunk on them they had only gorne in recently think there oil very stiff push them in and they slowly expand again will be putting these in soon just wondering what they were thats all there perfect condition the rubbers on them are still black and soft
the will e going in rear of ke55
the casting marks are goren need to open up were the base of the carby sits a bit and angle them so they can can flow straight on a \ angle in to the runner ins stead of L
What i have heard also is that there not that bad as they have a long straight wich pic the airspeed back up and all that.
yea i have a feeling it may well take me awile to get it running wel i may pass it to a dyno tuner to play around with it or me see if they can get me moving better then what ill be able to setup
Ok awesome info comeing up in this thread
1 quick q
Am i going to be running out of air ? with my 286 deg cam with me twin 3k carbs or should i be ok ?
Crow Cams grind in a 3k drag car that goes a little something like this,
Inlet opens 43 closes 71 Adv Duration 295
Exhaust opens 75 closes 43 Adv Duration 298
Inlet and Exhaust lobe lift .270".
Inlet and Exhaust Valve Lift .405"
found in a post
the only ting I'm scared of is if me 4k bottem end will hold 8k rpm only need to last till feb march
Also i think my twinsshould give me a bit more tunning flexibility and should help my down low under 3k which this car really wont be driven under 3k anyway
i don't no what one is what lol sorry
And i havent seen any cfm rating of these carbs my guess is they would flow around 150 % of a normall 4k carb as they only lose 2 ml of the troats but are much larger ports in the actual manifold helping the cfm
can u do 2 plz
one a 4k with extracctors with my cam twin 3k carbs 32ml inlet ports. 10.5.1 (going in by christmas)
5k 32 ml ports eg bp twin carbs and my cam with extractors 10.5.1 (Hopefully march)
4-1 extractors
u can play a bit with lil higer compression if ud like that would be good cheers
yes but u can email crow that what i did think they have there old info on there systems still.
Would be good To have a database of what pepople have used .
i will soon be fitting some hq shocks don't no what brand but they are red and made in the usa any ideas on what they could be seem very stif hard to press by hand there oil no gas i dnt think
