Hi I can only find a block from a diamler 2.5 v8 locally. I'm wondering if it's possible to use a pair of top ends from a high reving motorcycle 1000-1300 cc engines in the block? Finding Jaguar or diamler parts for that car would be way too expensive and I want to make good power. I don't know alot about engines and an trying to learn as I go.

The other option I have is to find a pair of v4 engines and try to mate them to make a 1.6-2.6 v8 engine I plan to turbo.

I have a 1973 Opel gt. The engine bay is very small. I would prefer to find a small v8 so the engine bay looks like a small version of the he corvette to match the outside of the car. I can find very powerful 4 cylinder engines that would make this very fast but I'd rather try to make it more of what I think Germany should have done with the corvette makers designingvthis. European v8 engines were small and very powerful compared to the American grunt in heavy cars. This car is very light. I think wn f1 sound is more appropriate for beating it's big brother in this baby corvette. Thanks please don't say out a big engine. The biggest is a 215 Buick but still needs modification so the 2.5 vi is the biggest. Any other small v8 under 3.1 I'm not aware of

If you have seen my other post, I'm trying to find a tiny v8. The 2.0 fiat/Alfa romeo and 2.5 diamler/Jaguar is the only options I could find but finding an engine to buy is impossible.

I've heard people connecting engines together. I'm wondering if I could do this with acouple of motorcycle v4 engines to make a small v8? Does anyone know if this is really possible? Putting a pair of 650-1300cc v4 engines together so I could fit it into my tiny Opel gt engine pay would be wonderful. Can qnyon chime in on what would be needed? Could the cranks be connected or would rhey need an adapter to connect them from output shaft to front of other engine with space in-between? Like I said, I have very little space in the engine bay.

You can do whatever you want, if budget permits.

Small V8's based around bike engines do exist. But are you prepared to pay well into 5 figures for an engine ?

One of many, but maybe one of the more accessible. All of the very custom work you are dreaming about, will be very very expensive to achieve. Does your budget permit ?
And are there any rules that may restrict what you're wanting to do ?

Anything is possible with enough time, money, skill and resources.

It's not clear you have enough of any of those to make it a realistic project for you.

Cylinder heads onto a completely different engine? Of course, I do it at least twice before breakfast. rofl Got any harder things you'd like to do?

There are other smaller V8s, typically quite old, so they do not 'make good power'. Given the queries you are asking, all you are going to do is end up with spending your money on a bunch of pieces which will not work.

If finding genuine Daimler heads is too expensive - then ALL of the other options are even more expensive. Additionally they need REAL engineering expertise - which is even more expensive. If the modifications to fit a Rover V8 are too much, then unfortunately so is EVERYTHING else.

Finding a top end it the engine is the problem. Not the price. I'm trying to avoid modifying the car body incase someone in the future wants to put it back to stock. I believe you are assuming this it to be made into qvrave car. While I do want to to be fun, I'm not going to race it. I want it to look similar to its big brother the corvette. That is the point.

What's your budget? Are you expecting to contribute anything other than money to this project?

There's nothing very compact about the CIH; any number of inline 4 cylinder engines could fit without modifying sheet metal, whereas any V8 is going to be very difficult. Why does it need to be a V8?

As already said, what you want is easy, if you can afford it. There are engines already out there.

OP, have you considered a 4.0/4.6 rover instead of the 3.5l/215ci?
