Helping my friends son. He has a 81 SS 440. I have a lot of parts but there from 87 Srv and up. Wondering if the 87 carb, boyesen double stage reeds I bought for my 90 Srv brand new would fit in his intake manifold. And carb. Thanks for any help.

Thanks, I did a lot of reading on this . And yes your right . Thanks again for the help with my carb switch out on that 90 srv to the 40mm round slide . Throttle junkie 35 help me out with parts. What a difference with that carb and exciter II secondary with 39 Helex. Can't keep the ski's on the ground. Only ran it three times. A little lean in mid range. I am done with all my surgerys so now I can ride. Thanks again for the jetting.
