Dyno day is almost here!
Been a long time coming! Way back in April of 2013 I broke my old stock block 462 in half on the street near my home.
https://uploads.tapatalk-cdn.com/202...da23286edb.jpg It was a block failure...split from main up through the cam tunnel. This old engine with a set of 64cc Eheads was powering my 3600 lb GTO to 9.8’s in the quarter. I swore I would never build another engine for it unless it was an aftermarket block. https://uploads.tapatalk-cdn.com/202...4f4e9fbae1.jpg In the meantime my wife and I found 80 acres of land we wanted so I stored the GTO and we purchased the land and I fenced it which pretty much took our extra money for closing and fencing. A year later we had some more savings and decided we wanted to live on our land because we loved it so much so we built a house and shop on it. Again no extra funds...I saved a couple bucks and bought an IAIIA block in 2017, about a year later I bought a set of heads, 2 intakes, shaft rockers, lifters... https://uploads.tapatalk-cdn.com/202...b11f67e525.jpg https://uploads.tapatalk-cdn.com/202...a0a2284011.jpg https://uploads.tapatalk-cdn.com/202...cec881715d.jpg https://uploads.tapatalk-cdn.com/202...8e07ee6bf8.jpg In 2019 I took the GTO to a chassis shop that mini tubbed it, rack and pinion steering, control arms, brakes, coil overs, crossmembers, tube core support, and a lot more roll cage. https://uploads.tapatalk-cdn.com/202...80e9293f72.jpg 2020 I decided it was time to start putting things together. I also decided the end result would be Mechanical Alcohol injected 535 CI so I needed an intake and sent a Gutsram I got with my wide ports to Hampton Blowers to get a top put on it... https://uploads.tapatalk-cdn.com/202...8c1b1a3388.jpg We bought a cam based on 12.5-1 Blown alcohol. https://uploads.tapatalk-cdn.com/202...afe7bd361d.jpg Here is what it looks like with the 8-71 and hat... https://uploads.tapatalk-cdn.com/202...b665e5c171.jpg But we are dynoing it built like this on gas and I will add the alcohol injected supercharger later... https://uploads.tapatalk-cdn.com/202...7be6f21b85.jpg What do you think this 380 CFM wide ported, 12.5:1, 535 ci engine should make on gas with the cam listed on the cam card with a 1050 dominator, Victor intake? We are dynoing Friday... Sent from my iPad using Tapatalk |
Congrats!
It's been a long time coming for you! |
First and foremost, im glad to see you're going injection and not carbs!!
That lobe separation looks a bit tight for a blower car in my opinion.. Last, im most impressed with what you did to your block! Thats a true racer right there.. |

I thought the same thing on LS of the cam but that is what my engine builder got as a recommendation from Comp...I figured it should have been at least 114. That blown up engine lasted a long time. I changed the oil in it and found a main cap dowel pin on the magnetic drain plug. I pulled the engine and found where it came from and pulled the cap and reinstalled it. Nothing looked out of place so I buttoned it up and I decided to take it for a rip down the Highway...it got just into high gear when it let go...even more impressive is it lunched the converter, broke the trans bellhousing, and took out the ring gear in the rear! |
Nice!
Who did the wide ports (they look cnc'd)? What valves are in them? |
Glad to hear its almost done. 👍

Where are you getting it dyno’d at?
|
You are going to have a great time with the new engine,congratulations. Engine looks bad to the bone, mean.
That engine blown must have been quite the experience. |

When the engine let go , did it look like that in the car or did it fall apart while lifting it out? Thats scary..
|
Engine looking good with the blower!
