I'm 5'11 and raced bikes for over 10 years and was a 1st Cat road racer for a fair few of those. Tack on a few extra years to that decade of racing and that's where I'm at right now.
Size wise, I'm dispropotionately 'all legs' - inseam ~34" and I ride very comfortably on a 58cm these days but even with the stock 11cm stem it's a tad short. Very comfy and relaxed but a tad short for what's needed on that bike. A 13 or 14cm stem should do the trick. For some reason, all the bike stores I went too and most of the guys in local clubs said I should be on a 56. Fark that, it'd be like being bent over to scratch my ankles when riding down the road... Maybe it's a US thing. Still haven't worked that one out.
Think about that 'elbow stretching'. If your joints are 'locked out' through reaching too far there's very little stress on that joint. Similarly, do a pushup and lock your arms out and hold for a significant amount of time. It aint your arms that are hurting. Try that with a significant bend in your arms.
The goal though isn't to lock out the elbows. The goal is to balance the weight across the bike and put the rider in a position in the best position for the desired type of riding. Nothing more, nothing less.
Yes, it's a real GM 502. One of the first ZZ502s that GM produced... a soon to be fuel injected 502.
... a 502 that drives a 4 speed Muncie, Moser engineering rear end with Eaton Posi, suspended by revalved QA-1 coilovers with independant compression/rebound and just to keep us comfy there's a fully restored interior.
The car was originally an SS with a 396. That motor needed work and didn't meet 'the plan' so it went to someone who wanted it.
You might be putting 500hp through the mouse but do you have 500+lb/ft of torque from 1,900 rpm? One of the big 'decisions' was what power plant we should throw in it... I could have gone with an LS6 (the LS7 wasn't around then, neither was the ZZ572) but the lack of neck snapping torque from any rpm was a deal breaker.
The plan was keep it classic, keep it simple... Make it look good, look fast and go fast but still keep it very streetable.
... well kind of. Carbs just don't do it for me though but the RAMJET intake on the GM spec fuel injection for that motor is too tall to fit under the hood. Yes, it does say 502 on the hood scoop. Gotta yank the intake manifold off the motor and measure to the hood to see in the Edlebrock multipoint fuel injection will fit.
Finding a 67 isn't that hard. Finding one with no rust, no bondo, no welded in quarter panels and is generally pretty straight is a little trickier. I didn't care about matching numbers engine/body... I just didn't want to spend a bunch of time doing bodywork and prep prior to paint. Finding one as clean as this at a reasonable price meant a trip from California to just north of Miami and a long road trip back.
Then again, finding a mid 90's 4th gen is easy... making it look like a V6 with no noticable tailpipes either side of the rear bumpers must have taken sometime. You sure there's a LT1 or LS1 motor in there?
I ride about 10 hours a week and have a very lucrative job. Thanks for asking.
Just for a point of reference, that frame that's hanging off the wall with the big black seatpost is the one that I'm riding in my avatar at ~ 28+mph. Yeah - it's mine
Note the late 80's Campag delta brakes (croce d'aune) - I still have the Campag Shamal wheels, Bell vortex helmet and US team issue Descente ribbed 'batsuit' too. Just don't ask how an english lad got that rare piece of clothing... especially one with no bike 'experience'
If you're really interested there's a really nice FSA carbon seatpost on the red Cannondale hi-mod that's gonna be swapped out soon for an aluminum one - swapped not because of the material but because I don't like the big setback on that post and the lack of easy access on the bolts and yeah, it has real carbon on it and it weighs f**k all.
