correct me if I am wrong guys,but both are big blocks so the swap is very simple,just a few bolts <img src="/ubbthreads/images/icons/smile.gif" alt="" />,stuff like engine mounts and transmission will bolt up with no problem.Now the crank part...I have no clue

anybody out there got a set of heads kicking around with casting 7a(409147)from 1972 350 ?

Ok guys,I do have a 1968 olds 98 with stock 403 in it for now,the exhaust manifold on it looks like from a 403 with crossover pipe to right side.Us I understand that a big block manifold (LH "S") will bolt up to small block and then I can run dual exhaust to the back,since it was designed for a big car like mine anyways,or am I missing something here? p.s. Scott,that guy from 442.com with delta 88 is willing to part with that manifold for only 800.00 usd <img src="/ubbthreads/images/icons/smile.gif" alt="" />

thanx Scott,already send him an email....you never know <img src="/ubbthreads/images/icons/smile.gif" alt="" /> any ideas what it might be worth ?

they fit small block olds for dual exhaust and were made 65-70,there supossed to be a big "S" casted on top of the first port.

Looking for a exhaust manifold LH casting 384895 "S" or 393233 "S" olds.If you have it,let me know.Thanx

You should try your local machine shop,they usually have a good selection of frost plugs and you may not have to buy a whole set.

rocketraider,I do have dual exhaust at the moment with a very nasty bent on drivers side with a manifold casting A, which comes out in the centre,where about does the casting S comes out? Is it at the back? And maybe you know where I can find one and what do they go for?I appreciate your time guys,very informative.thanx

Does anybody know which headers to use on olds98 with a small block(350 olds) in it? Will cutlass style headers fit in there ??? Since there are no listings for any headers for full size olds... Any sugestions or opinions ??? <img src="/ubbthreads/images/icons/confused.gif" alt="" />
