- We work on doing the “dry assembly” on my MGB performance build, and show you my engine stand, which is an unusual one. We start by looking at some if the parts going into it, like the pistons, rods, crankshaft and harmonic balancer. We then check that it was machined to the clearances I’m looking for by using plastic-gauge on the main and rod beatings to verify them. We then measure the assembled piston to deck height so I can calculate how much to have the block decked to achieve the desired compression ratio

Very good, I built mine recently, same components except forged pistons and steel main caps on 2 and 3. I was able to use my larger factory main caps with arp studs on 1 and 4. I just have a factory flywheel as it is all I had, 20 pounds… but I plan to change this in the future..
I had larger valves installed and we flow benched the head, I’m running yellow terra roller rockers and custom length/stronger pushrods with the shorter/lighter followers.. the cam and head were designed together to give amazing torque as I use the car for dirt rallies, I get about 140 ft/lb at 4100 and 140hp at 5400… running twin SUs.. my extractors are a bit long.. I also have a close ratio gearbox… I sooo love my engine :)
My last engine was close to what this one will be, and my BGT only weighs in at 2100 lbs, so I enjoyed it. I’ve been running an almost stock used engine I had laying around just to have it running, and I really miss having a bit more.
Yea! Race engine build time.
It’s taken long enough since you and I pulled it out hasn’t it? You will have to come over to take it for a drive sometime after it’s up and running
Outstanding video and presentation.
Glad you enjoyed it
Geat Video Rob, very well done. .I think I have the gram scale as you
I hope you have a better one than I have. Mine is a cheapie that bought for other reasons where accuracy wasn’t terribly important 😁
Great video. Have you ever worked wuth an engine built by Hap Waldrop?
I actually installed one if his engines into a local vintage race MGB once
I noticed you stand your crankshaft on their ends rather than laying them on their side. Is there a reason? I would be worried about them getting knocked over.
Yes, I was taught to always store them that way and never lay them down. You have to take precautions to not knock them over though. You can do a search for why and find lots of articles about it, but basically they can deflect a bit and no longer be straight if stored on their side without proper support in the middle to insure they stay straight.
ARP dose make the 5 main bolt kit part number 205-5002
Nothing shows on their website, and nothing found on the part number your giving (either on the ARP site, or google search) Maybe they had them at one time, but appears they don’t anymore. They only list 3 main stud kit and 5 main stud kit ( i already have) but no listing for 5 main bolt kit. ☹️
@@mgbgtguy i mad a mistake the part number is 206-5002
Funny, the ARP website won’t come up with it if you look it up by application. But that part number is good 👍🏻 and description says MGB 5 main bolt kit. Thanks
@@mgbgtguy i hope this helps out
Yes it did, got them on order 👍🏻
