Valid reasons why I should not plug in a Chevy small block

[nesslar]

Wil,
Just 'cuz it's kinda' fun, of course, as you know.

And...BTW.... the Chevy small block, even if cast-iron with aluminum heads, is not much heavier ( if at all) to our much vaunted , all-alloy flat six.

Having lifted (with help) many a 911 engine, and many a SBC, with iron and aluminum heads, I disagree.

A 911 engine (say a stock 3.0 or 3.2) dressed with intake and exhaust, is definitely lighter than a SBC with aluminum heads in the same configuration.

V8 in 911, who cares? 911s are plentiful and cheap these days (74-89) and there are lots of scrappy ones around. Have at it and have fun. But no way does the SBC weigh the same or less than the stock engine in any of those years. Nope.

And, BTW, this is of course a trolling thread, and one of the least creative ones, but so what, it's been a while since the "Could have had a V8" thread.

You put the SBC into the 951. Better HP/Torque and more reliable.

The 951 engine can be tuned up to 300hp with bolt-ons which is probably a lot cheaper than doing the SBC conversion... for that matter if you must have a SBC Porsche it is a lot cheaper to find one that has already been done and depreciated. YMMV

I have an old German car (79 911SC) that is fun to drive and shift's hard like Dad's 49 Ford pick-up truck. I have also noticed that members of this forum like to knock SC's down in terms of market value when they are up for sale?

In my opinion my 911SC is underpowered, has a noisy valve train, leaks oil like a British motorbike and it costs a fortune to rebuild the engine.

Are there valid reasons why I should not install a 350 Chevy V8 next year? And please don't say it will reduce the value.

Will....Cobras were first? Hardly. You forget Sidney Allard...

BTW, the 3.5 liter Brit motor (ex GM) aluminum v8 is an interesting idea with some potential, but it has some cooling & 'breathing' limitations that limit power potential. I tried a lot with my TR8, but the best it could do and still be streetable was 270-320 hp. The newer aluminum chevy motors (and various aluminum crate motors) have a LOT more potential for about the same weight.

I agree with you, but isn't that enough for our pseudo-sitch here? Even it was a later euro car (3.0), it would be a nice step up in HP, and I would imagine a hefty boost to torque across the band...

CMDR, drop the V8 into your SC, and I'll send you a Gruppe B sticker to replace your SCWDP sticker. That alone will up your HP 5%.

why is it only Chevy's that get considered.? A small block Ford is very compact and the cast iron versions are a hundred pounds lighter than the small block chevy's . Aluminum heads are available too. I would like to do the swap into my 944 if conversion parts were readily available, but mostly because the timing belt's on the 944 engine look sooooo narrow.

A 3 liter 911 engine fully dressed weighs aboyt 425 lbs.
A fully dressed 930 engine weights over 500 lbs.
A chebby sb with headers and an aluminum intake manfold weighs 475 lbs, with aluminum heads about 430 lbs.

But,, a 911 should never have less than 6 main bearings which rules out the chebby.
