So I'm partway through building my oppy to run alcohol and I've found myself questioning some of the expenses on certain components if they are absolutely necessary.
First off im not going cheap on the build, I just want to be sure I'm justified in every expense. I already have the Arc rods, and Im ordering mod 28 pistons, wrist pins this friday. Arc billet flywheel is on the list. I am using an MSD ignition/coils with an Tillotson HL-360D Carb and custom intake (for the side draft conversion).
My questionable items are not so much major break points but more a question of performance. I'm on a bit of a time crunch as our test/tune track day is May 7th. The biggest thing is the cam, I can see how much of an improvement the different lift would be but is it needed? has anyone every lobed or broke the stock cam? If I get a cam it'll be about 250 shipped and I'll end up reinforcing the rest of the valvetrain on it, I.E. bronze valve guides, Stainless valves stock size, stronger valve springs and billet keepers not to mention the addition machine cost if the heads need relief cuts. I believe the lift on the new cam would be around .360. I know it'll be a big power difference but how strong is the stock cam?
P.S. this is NOT just a cam thread, it's for the engine build. more questions to come as it progresses.
