Re: Perry's Drag Race MGB is getting a SBC engine now !
Perry, Some drag cars stateside like E85. 85% Ethanol/15%Petrol. Less corrosive than Methanol. Cheap, as it is used in Flex fuel cars and available at gas pumps.You would need almost twice as big of jets and steel needles and seats. Also any rubber lines rated for Ethanol.

Hi Jim
The SBC with the ally Brodix heads will possibly be lighter than the blown Rover engine. Or at least the same weight I think. Pel |

Re: Perry's Drag Race MGB is getting a SBC engine now !
Perry, I look forward to your build. I am getting ready to build an engine for a vintage nascar I have. I am going to intentionally keep it to 350 just to keep in line with how the cars were raced. I plan to start buying parts at the begining of the year. This is the block I will likelly start with:

Re: Perry's Drag Race MGB is getting a SBC engine now !
That is neat, but probably a little more advanced then I want to go on a 1990 Nascar. It won't be a 100% erra but mostly so.

Re: Perry's Drag Race MGB is getting a SBC engine now !
Great choice, the Iron Man. He used to destroy Late Model Sportsman right here in Kingsport, TN back in the early 70s. One of the best short track racers ever, if not the best. His home is only about an hour & 15 minutes from here over in Asheville, NC.
Of course, if I were doing what you are, Gary, I would have to back up 3-4 years to honor one of the most wide open, hardest charging drivers. |
Re: Perry's Drag Race MGB is getting a SBC engine now !
BTW this will be a full ground up build. I took the body panels off, and it is at the sand blasters right now:

Re: Perry's Drag Race MGB is getting a SBC engine now !
The new SBC engine for the MGB has now taken a turn in the overall plan for the build ??
I have just ordered a new Dart SHP engine block for the build. There were several factors that lead me to this decision. But I think this is the next best course of action for me now. My old 4 bolt block was overbored to +60 thou and I'm not happy that this old block will stand up to the abuse I intend to give it ? Eventually it will be supercharged, but until I can afford a new blower it will have to put up with a lot of Nitrous abuse. I took some time to look at the list of parts I have collected in the last 18 months and saw that everything was brand new apart from 50 year old engine block. The carbs will be the only things that are not brand new for this build now. And if I can find some money in the next 6 months they may also get replaced with new tuned and matched items? The new Dart block can be bored to give me a nice 430ci motor while still having bore walls 1/4" thick? The MGB has been off track for 17 months now so I guess another 4-6 months isnt going to kill me eh ? I just want this to be my last engine build, but also my first ever NEW engine build :) When the new block arrives I will make a final decision on the crank + rods + pistons so i can finish the buuld. When the new block arrives in 2 weeks i will also need to have it fitted with cam bearings as well as making a decision on the final bore size and deck height. I'm hoping that by mid to late April I can start bolting stuff together :) Regrds to all Perry |

Re: Perry's Drag Race MGB is getting a SBC engine now !
Perry, Thanks for keeping us updated! I'm curious as to how the Speedway mounts will work out in the MGB.

Re: Perry's Drag Race MGB is getting a SBC engine now !
Wondering what displacement/bore/stroke you are thinking towards? Redline? Lots of potential there.

Re: Perry's Drag Race MGB is getting a SBC engine now !
Hi Jim!
I'm going for a tame 383 build on this new engine. The new block is capable of running much more CI but I dont think i will need it? |

Re: Perry's Drag Race MGB is getting a SBC engine now !
Carl thinks using the 400 block with the 350 crank would be a better drag engine, (room for bigger valves and lower piston speed.)

Re: Perry's Drag Race MGB is getting a SBC engine now !
AND, the shorter stroke. We already have traction issues (maybe not Perry), so I tend to prefer short stroke, free revving engines that move the power farther up the range. I can't use 300 lb-ft of torque at 1000rpm.
Well, now that Perry has purchased an aftermarket block, he can build anything he wants all the way up to a 440 cubic inch small block! The 377 vs 383 dilemma. Quote: |
