I know everyone is tired of the old SBC but there is a reason they were put in everything. The first one I did back in the 70's was done with a stick welder and a BFH. Had to "massage" the firewall a bit to fit the Powerglide that I originally installed. No modifications necessary to the crossmember and I ran the exhaust on the inside of the frame rails by using the rams horn exhaust. The swap cost virtually nothing as it was all parts that were laying around. It was heavy in the front as it had the full iron complement of intake, water pump, heads and exhaust. With my current swap of aluminum heads, tube headers, water pump and intake the minimal weight gain is worth all the performance. Cost? I never mention what I have in my builds as I might want to sell them some day but my Scottish father would be proud. I do have a full complement of shop tools as it is also necessary for my business but most of what I do could be done without them, it would just add to the cost. I can tell you that the most expensive thing I have ever spent on a MG was the AFR heads for my big block. Thankfully, they were not damaged when the engine blew! I replaced it with another SBC that I had laying around. The SBC is a much better choice for the MGB but I may put it back in with a milder cam and quiet exhaust.....
I wasn't going to comment as everyone has their opinion and it's based on a lot of factors. Cost is one of my big things and the reason I left Ford many years ago. The V6's are cool and the Rover/Olds/Buick V8 is a compact power unit but bang for the buck can't be beat by anything else except possibly the LS. I keep looking at them and eventually will pull the trigger on one.
Help me decide my conversion
