Re: MGB GT V8 Conversion
Good to have your insight Jim, and thanks Carl, I don't think I've spent too much time on that page yet.
Not really thinking it's necessary, but I thought it would be fun so I figured I'd give it a try. This is mostly an excuse for me to play with power tools and sheet metal. Cutting big holes in the firewall had definitely provided that. Nothing is really nailed down (on the car or in my head) at this point so going a bit forward is still in the playbook. I've already notched out my cross member to allow for it to move forward if necessary. I'm also considering changing up the steering shaft flange location at the firewall similar to in Dan Masters' car. Terry Schulte's car caught my eye: [www.britishv8.org] His modifications to the steering are about what I had in mind. Edited 2 time(s). Last edit at 04/30/2020 08:53AM by Nukem. |

Re: MGB GT V8 Conversion
Terry's car is a good example of a minimalist installation of the Buick 300 where the stock hood closes on the engine. I don't think the builder had to do much other than move the firewall mount for the steering down about 1-1/2" and that was done with a minimum of cutting. Probably had to trim the right side shelf back a little for head clearance as well but I don't remember. Lucky it's a GT so you had no need to brace the doors before cutting all that out. Just remember this, Virtually every bit of extra space you take for the engine will end up coming out of the area for your right foot. Which pretty much has to stay on the gas pedal. That can make for unpleasant driving if not carefully thought out.

Re: MGB GT V8 Conversion
I think you are correct.
Changing the subject a little: glass is out and all the brightwork is off. I'm contemplating having the shell media blasted, but I've started peeling back some of the layers of previous rust repairs, bodywork and resprays anyway. Most of the previous rust repairs were not carried out properly, with the patches welded in over the original rusted panels in some cases. Overall the shell is in reasonable shape though, not nearly as bad as some of the pictures in my Haynes restoration manual. Edited 2 time(s). Last edit at 05/02/2020 06:58PM by Nukem. |

Re: MGB GT V8 Conversion
I expect to take at least a little flak for this, but here is a fun shot of my mate's Z31 wheels on my MGB rear axle. Just trying to get an idea of how much tire I can fit and his wheels were handy, so don't take this too seriously...
Wheels are 17x9 wearing 245/40/R17 Clearance to the bump stops is tight but they bolt up and spin freely, so they might actually work with a little different offset, better axle location, and fit under some relatively moderate flares. Edited 1 time(s). Last edit at 06/04/2020 01:00PM by Nukem. |

Re: MGB GT V8 Conversion
Good looking wheels actually.

Re: MGB GT V8 Conversion
I thought I would hate them on the MG but I was surprised when I didn't.
I think they look more at home on my mate's Nissan I tried his rear wheels which are 275s yesterday and they almost fit as is, and would fit pretty easily with mild flares and a little different offset (or a little wider rear track from an 8.8) Edited 1 time(s).

Re: MGB GT V8 Conversion
Doesn't the diameter of the 275's make the back of the sit a bit high?

Re: MGB GT V8 Conversion
I think the 275s were 275/35, so about an inch larger in diameter than the stock wheels and about the same as the 245's. Should be manageable but a little taller than ideal.

Re: MGB GT V8 Conversion
I'm really glad I just read these 2 pages about not slamming that engine to the firewall. I wasn't real excited about that anyway. Thanks guys

Re: MGB GT V8 Conversion
I'd suggest in the process of changing the lower column attachment to the firewall that you consider doing an EPS at the same time. There's a thread on it in this forum.
