[Benny771]

Well? What do you think?

No its not mine.

Needs to sit a little lower, but maybe it's raised because of engine weight? Otherwise it's a good looking car. I don't mind a V8.

On second thought, a flat six must weigh as much as a small V8?

[lin7310948]

needs to get rid of the carburetor and add efi. the distributor is on the wrong end for a sbc. is it a ford v8?

[RarlyL8]

A 930 engine weighs more than a modern V8.

I do believe that is a Buick 215 C.I.D. V8, all aluminum no less! Just Goggled images to be a little more sure of this.

that seems almost counterproductive if you are looking for much power in a v8 conversion.

[DDDD]

I don't like this particular conversion because of the way they did the front hood but in general I like the concept of adding a V8. I would not do it to every porsche but if you have one that needs an engine and is not a concours car than why not.

An all aluminium block and head V8 weighs 300 lbs.
A Porsche 3.3 with turbo trimmings weighs and intercooler weighs 500 lbs.
A Porsche magnesium 2.7 weighs 386 lbs.

A V8 can comfortably put 550 hp to the wheels with no lag. At a much lower cost...

It just makes so much sense.

That being said, I will always keep the 3.0 engine in my 1976 930.

If I had a regular 911 however I would be willing to do it.

Pelicans,

I stuffed small block chevys into two different long hood 911s. Cast iron blocks with aluminum heads. REALLY bumped the car up into a different performance league. Power everywhere. Made the handling in the short wheel based 911 very tricky! It was hard to judge where the limits of rear tire adhesion were.

Swap is not that hard, but getting cooling system correct is obviously mandatory. Opening up the hood like this guy did is best route for cooling. Lottsa attention to detail contributes to a clean installation. Gotta use AT LEAST a 915 trans or better and a strong clutch. As long as the clutch is biting, will absolutely shred tires. (Broke a few cv joints jumping on it in corners.) Bought my kits from Rod Simpson Hybrids, www.porschev.com (no affiliation). A good guy that regularly advertises in EXCELLENCE magazine.

Agreed with DDDD, I'm all for a 'good' conversion, esp. if the situation dictates it (not just for heck of it). This one is, well, mostly.

That hood that's his "pride and joy" makes me want to vomit / hurl / upchuck / barf / puke / blow chunks. The ride height is 'meh' and the wheels / balloon tires need help. Interior looks real nice, and engine bay looks like a hoot. Sounds like it'll go real good. Offenhauser valve cover inscription - cool.

Biggest problem? Could that guy BE any bigger a DORK??? Sorry, hope you're not on here 8-). Was painful to listen to...

+1 on his pride and joy. Add to the descriptive vocabulary spew and regurgitate. I guess there will always be people who consider engine swaps a positive modification, but I for one am too much of a purest (though I do admit once in my life seriously considering a Buick 215 V8 conversion in my '72 MGB). Never went there; crashed the car instead. Ouch...

Hello there DDDD,
Getting 550hp out of a limited production early 1960's 215 C.I.D. Buick, would not be easy or cheap. Hot rod parts were available for awhile, but now.....???
If you go with a newer Chev. S.B. now your talking cheap & easy H.P., but a bigger & heavier package overall.
I say keep the Porsche in the Porsche, and put the Chevy's where they belong...in a Jaguar!!
But I'm bias so....go figure.

The weight numbers I was listing where for a modern aluminium corvette engine with EFI included, I would not put a 1960 Buick engine in anything, but different strokes...

[WANNA930]

You can buy straight from a GM dealer a real 500hp all aluminum LS engine for about $5500. SDPC has deals all the time. They weigh under 400lbs dressed. Actually probably the best engine ever made as far as performance to weight and cost but since it is a GM piece it will never get the praise it deserves.

The buick 215 was one of the biggest mistakes GM ever made as they sold the rights to Rover. They used those little engines up until a couple years ago in a lot of English built cars. Some all aluminum. Not a bad engine but also not the 1st choice for performance.

Hey spend $30k on a 930 engine to achieve the same level of performance?? But I agree that it will always be looked at a as crossbreed. Close the hood and hit the gas and you might forget it???

[Hayabusa]

Totally defeats the marque!

That's like putting a supercharged Acura TSX engine in Ferrari,, ridiculous!

[Miguel Antonett]

No, thanks!

Yeah, that's basically a rover block, which started life at around 150hp with the 3.5, then up to 180hp for the 3.9, 200hp with the 4.2's (this block had problems breaking cranks), and finally 217hp for the 4.6, and this block had cross bolted mains. East Coast Rover builds that block into a 5.2 with 340HP, but I'm thinking that's $30k motor. So, to get up to 500hp I'm guessing would be pushing it, and very expensive.

Still plenty of hotrod parts for this block though.
