Re: My latest project, MGB
If I had it to do again I would go small block ford but I got an incredibly good deal on a 4.6 rover built the way I wanted from a friend

Re: My latest project, MGB
Consider the Buick 300 instead of the Rover.

Re: My latest project, MGB
Jim, I have considered the Buick supercharged V6. Is that the engine you refer too? Or, the old 64-66 aluminum block?

Re: My latest project, MGB
I'd take the 300 for an mgb anytime. In fact I'm currently building two of them with 350/340 cranks, TA heads, NASCAR rods and cerakote block paint. Deck is 9/16" taller than Rover, iron block is stronger, more durable.

Re: My latest project, MGB
What displacement do you get with the crank swap? What kind of streetable power can you get from the combo?

Re: My latest project, MGB
Jim, 340 with 3.75 bore, 350 with 3.8 bore. With the T/A heads and good cam should be easy to get 350-400HP. There was a twin turbo 350 that made over 1000Hp.

Re: My latest project, MGB
I’m swimming in 1000 1979 MGB pieces in my garage, deeply frustrated by the costs involved in rebuilding a Rover V8. Here’s some details:
[forum.britishv8.org] If you’re thinking about a Rover V8 and are at all cost-sensitive, you should wait until the perfect rover engine turns up— known history, low mileage, no overheating, no slipped liner, no cracks. I think there’s one like that somewhere on earth, but I’m not certain. I bought two junkyard 4.0/4.6 engines with enough good parts for one, but am still many thousands into machine shop costs. Making a performance RV8 doesn’t make much sense, but then again, neither does owning an LBC, or a boat, or a horse, etc. Your v6 idea may be a great one. I’ll be watching this thread enviously.

My preliminary measurements are quite positive. One of the advantages to the newer 3.6 V6 is that exhaust manifolds are an integral part of the heads. Add that is a 60° engine, making it even more attractive. 300+ hp is all I want in this lightweight! I was fortunate enough to get an excellent buy with all accessories and ecm & harness. 35K miles. I will have to build mounts and, God knows what else but, I love a challenge. Great to start with a solid car! I may even stick with the 6 speed. Rear differential and front and rear suspension are still in planning stage. I am sure there will be a combination of tubbing and flairs 😎 GJS |

Re: My latest project, MGB
Glad you love a challenge, cause you will be blazing a new trail with that engine in a B. IMO, the exhaust may well be the easiest part of the swap.
Looking forward to it! |

Re: My latest project, MGB
I wanted a Dana 44 rear end from a C4 Corvette to replace the Dana 36 I had in my car. The rear ends by themselves were going for $1200 but I found a C4 minus engine and trans advertised for $1000. I bought it for $800 and parted out the rest of the car for $1300. Got the rear end and put $500 in my pocket. The deals are out there if you get creative.
