68 Yenco clone

[69Tom]

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.

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???

Cool!.
I've always admired the Chevy V8 Monaros from afar...and their 'Chevy SS' brothers!.
Do you now or have you ever owned any GTS 327 or 350 cars?!.

Welcome aboard Chris!.

I believe the connecting rods were <span style="text-decoration: underline">3/8&quot; dimple </span>rods in 1968 and it was a solid lifter flat tappet camshaft.

Kurt,

Ok then let me ask this, were they even designated 4 bolt blocks, I remember that there was an LS6 cam that was about 520 lift and I think that also came in the L88.
So then, did an L88 just come in the Corvette ???

Cheers: auschris

I suspect you'll be looking for a four bolt block. The L88 in the first design configuration is a long way away from the L72 and the second design L88 is even further away (more radical). I think though in your own best interests, it might be good to start gathering printed info (books, magazines, etc.) on these cars and other Chevrolets of the era. Even though I do this for a living, I'd really suggest you dig deeply into the research part of the equation first (just like teachers I guess -- in reference to one of your earlier comments). If you're determined to build an accurate clone, there's still a rather steep learning curve that is likely going to be far greater than a few questions and answers posted here.

Best of luck.

Pete,

I had a 1968 HK Monaro 186 cubic inch 6cyl 4 speed that I got for my then wife.
I have built many for others and came oh so close to buying a mint 350 HQ 4 speed one time. Tried to buy one before I came here but those available were too expensive instead I brought over a HX one tonner (cab chassis) that I have built into a super gas/pro street car.
