    Aluminum absorbs more harmonic's then cast Iron will. But some people have built some very wicked iron horse's. Tom Nelson racing engine's, Morris racing engine's, and Moran racing engine's. These guys are masters at boosted engine's.

    HotRodRivi, look at the first picture on the second row of picture's. No on cam, it's driven by the crank and gear drived from there.

    That aluminum block is solid and the pro charger is ran off the crankshaft

    Can you order the ta block in solid or is that a 1 off deal?

    Your best answer on that for that question would come directly from TA


    As for Mike, tell them you have questions about a solid Tomahawk.

    For all out racing with Alcohol or nitro methane i recommend aluminum. WE are not close to making power yet. Seems we are dissipating too much heat or just not building enough. We've had very low exhaust numbers and you can actually put your hand anywhere on the motor or exhaust after the run. We just keep leaning it out. Also for strip only, no water saves a lot of time and space. No radiator, pump,hoses,fittings, and no water leaks anywhere. Thats another reason to run alcohol in aluminum for track only racing.

    The reason for iron is they make more power, but I have not seen one in blown top fuel for 40+ years. I just want Mike to make an iron race block for the street and strip!

    thanks for the reply.. I knew the iron blocks made more power, but was just looking at the ability to possibly fix it if it were to get hurt. I was thinking billet though and hadn't even thought about the water. best of luck on your project.

    Seems like there are a few questions I didn't answer, The Aluminum block pictured is raised cam, That is one of the reasons we are building new raised port heads. Pushrods will not be laid over sooo much!

    Our aluminum block is SOLID as is the second block we ordered. The heads will be billet also.

    Who is doing the billet heads?

    I guess I never answered this post. I did the billet heads. Out of the box, 534 cfm. More than enough for Nostalgia Top Fuel. Blown Alcohol Motor will probably be first in the dragster.

    Didnt some one build a nostalga dragster with the same setup on a Tomahawk?

    John Everett knows everyone in that class. If a Buick was there and competetive he would know. John had a couple moves across the country and plenty of work on top of that in the last few years that set his race ambitions back. It looks like he is getting things together for racing. I believe a Blown Alcohol motor is in the making. We are finally getting another motor together for the Dyno, naturally aspirated with the Billet Heads. Some very exciting news and numbers are coming this summer!

    I remember a nostalga dragster being built with the same crank driven super charger. They were having tire issues and were getting the right tires made someware. They probably were not excited about the results or would have posted more follow up.
