1987 Iowa Spree. Vin # confirms.

25 Mph.

Earlier post suggests using a 1985 pipe because of better flow? (current pipe is one uniform thickness from port to muffler with no washer restrictor
)
Opinions please

An earlier post suggests Iowa Spree could have different gearing? Does anybody know for sure?

Thanks for having this site, it has been really great reading and very helpful so far

respect,

Dave

yeah getting a different pipe will help you greatly. i could be wrong but This Guy is parting out a 85 non-iowa spree. he should have a pipe and he wouldn't scam you on price.

It also looks like the intake and exhaust ports are a little different. The timing is a few degrees off for the Iowa. The compression is also a little lower.
