Thread: Edelbrock multi-carb intake for early Ford 6

is your 170 a solid lifter 170?.. my best advice would be to leave it stock, but be on the lookout for a 200.. being a 170 it's a bit diffrent and only 2 years were 7 main bearing. distributor is diffrent than a 200-250 so the only room for upgrade is pertonix ignition, and you'll always be riddled with it being a loadomatic distributor, which won't be happy with straight ported vac for your 3 carb setup, I'v heard you can turn down the area on a 200/250 shaft to fit a 170 but I'v never done it.... 3 Autolite 1100's are what I'd reccomend you run on the 170, with a progressive linkage.. seriously, I'd be on the lookout for a 200. after '65 they were all 7 main bearing, and with the proper valve train and induction, can spin 7,500 RPM's easilly ( being a speedster, I'm sure that's a benefit ), and many mustangs get V8 conversions... a 170 head will work on a 200 with some work enlarging the valves, and that will increase the compression.. if it's a solid lifter engine, then you got adjustable rockers.. most all 200's are 1.5 non adjustable rockers.. just make sure you transfer the adjustable rockers with you, can mill the head for compression and adjust for it.. if you pull the head off and it's got a steel shim gasket under it.. have the head milled .025.. the old shim gaskets were .025 compressed, and composite gaskets are .045-.055 compressed.. the steel shim gaskets are no longer available so without the milled head, compression would drop

Here's a good place to get a lot of info too
