68 Yenco clone

auschris001 · #1 05-04-2010, 04:44 PM

Hi Guys and galls,

I am new in this site and need some help as to what is an acceptable mod and what is a no-no for a Yenco. I am restoring a 68 comaro and so far have the correct snorkel hood, a 427 with patriot heads, a t400, and 12 bolt rear with 4 leaf springs and 4 wheel discs. I am looking for a genuine block and heads to go with a powerglide to put in at a later stage.
I have the gauge console,tictoc tack and 140 speedo and intend to paint it matador red.

my question is what is acceptable ?? headders, brakes,ect and what is not like paint, trans, hood, decals, wheels.

Cheers: auschris

Not trying to be a smarta** - but my first suggestion would be that you spell it correctly - Yenko rather than Yenco.

Welcome to the site. There can be a pretty steep learning curve here. For starters it's Yenko with a "k".

You'll find it can be tricky building a socailly acceptable clone. I would recommend you build the car the way you want to and not worry about anything else. I personally feel you could just try and keep it as a "period build" using all the parts which would be correct to a certain time-line. Say speed parts form 1968-1970 for example. it doesn't have to be a Yenko Clone to be cool!

Got any pics of your project?

Guys,

sorry about the spelling, still learning American english Yenko see there I did it!!! I swear it's spelt that way in Australia.
I think the main thing I am thinking is that a good 68 Comaro ss clone is worth say $50K and a good Yenko would be $100K give or take. My point is that for a few more bucks getting those main parts that make it a Yenko should be worth it in the long run.

Yes I agree that it should be period correct for the ss or ss/rs
and I think things like wheels that can be changed easily I can get away with but the core parts I want to try keep correct. I just need a starter list on what Yenko did in 1968 as I am hearing different stories.

Cheers: auschris

ps:I will post some pics soon (have to reduce size)

Chris-

Perhaps a Yenko clone is worth $100K in Australia, but you'd be hard pressed to get that kind of money for one here. I've noticed COPO clones going for as low as $40-45K as of late.

I think that's why the others above stated as they did. You're probably better off making the car as you want it. If that's a Yenko, then, so be it, but I'd certainly not do it because you think it's going to increase the value of your car.

Someone else should be able to chime in with what Yenko did. There's also a few good books out there with are very informative.

Not trying to be a smart a$$ but, no respectable Yenko clone would have a Powerglide either.

Guys,

This is the feedback I need to hear as it sounds like I am getting the wrong info, its more me being a dumbass when it comes to these cars so here goes with a couple more questions.

Q, Was a powerglide with a manual valve body an option in a 68 SS or rs ?? (i think they called it a torque drive)

Q is a T400 acceptable as I think they came in 69 not 68

Q is it better to go long or short water pump as I believe these were 427 corvette engines.

Q what was the difference between the L88 and the L72, my thought was the L88 was a 4 bolt with 7/16 rods, 11.1 forged pistons and closed chamber rectangular port aluminum heads.

Cheers: Chris

T400 was only an option in 1969, as far as I know. 4-speeds only in 1968.

An L72 has iron heads.

From 1965-1968, BB Chevy engines used the 'short leg' water pump on all passenger cars & the Corvette. Should be pump # 3856284. In 1969, L72 engines on passenger cars had a different pump than the Corvette.

Now that you've learned how to spell "Yenko", it's CAMARO. [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img]

Thanks Tom,

These are such a cool car and I just want the main parts/theme right.

So if the L72 had iron heads were they still closed chamber rectangle port (where did the aluminum head fit in the picture). and did they have a solid or hydraulic cam ??
someone also said they had a 780 vacuum holley.
and was the L72 a 4 bolt steel crank deal???
