does anyone give me an idea about the cam choices.
(my engine combo is 383 cu.in 3.80 stroke nodular crank,
6'' 4130 l-beam rods flat top hypereutetec pistons,
afr195cc heads with 74cc combustion camber, comp ratio
9.98-1 intake and carb combo is 4 weber44IDF on individual runners manifold)
l want to use hydraulic roller butl dont know if it must be single pattern or dual pattern.which one will be work better with the 44ıdf weber any idea will be very helpfull

Do a search for cam techniques , based is florida . They are the folks you want to talk to , and they are quite reasonable . There is an online data sheet you can fill out and they will respond with a suitable cam for your particular application .

where did you buy your sidedraft dcoe system l think you use moon crossram manifold with 45dcoe.
ı wanted to buy a complete crosram system from inglese induction but the price was $4600+350 for vacuum porting.too expencive.and inglese says that single pattren cam works better with individual systems

Inglese is indeed VERY expensive , I purchased my manifold from Moon and built the system myself .You can save a great deal of money going this route . Cam Techniques grinds all the cams for Inglese , and indeed the single pattern is the cam of choice for IR systems .

do you know where can ı buy the complete linkage parts.
if ı can find it ı will try to built the crossram system by myself and do you have the pictures of your system do you built vacuum ports?

I dont know whats wrong with my keyboard .(&^#305) means ( I ). anyway did you produce vacuum ports on your
moon manifold. if you have a pictures of your set up you can e-mail to ( celal@paneldesign.com ).I found a complete crossram system from pierce manifods the price looks reasonable than the inglese. its only $3000 but they do not produce vacuum ports on the manifold.

glad to see some one is still using them ,its a nice peice huh ,well i would have went with a 64cc head but thats me,i would put a split lift-splitduration roller cam in it some were around 488/510 or 510/533 you will need a converter to hold it tho,just ask your cam maker what you should use ,i like comp cams but crane is great to ,wish you the best with it

The individual runner systems do not like split duration cams and are very sensitive to duration numbers . The weber setup can be run with a stock converter with no problems . Cam techniques specializes in profiles for use with these type systems . The IR system is very responsive and a LOT of fun to drive .

last week I talked to compcams and ı gave my engine combo to them. and they offer me a dual pattren extreme energy cam but I know that the single pattren cam works better than the dual pattren on ir system thats why inglese always offer single pattren cam with their system.when I asked to comp cams, why did you offer me a dual pattren cam instead of single one they told me that the afr heads exhaust ports doesnt flow as much as intakes. buy the way I try to reach the cam teq I sent my combo but I didnt get any answer. I am confused..
