This should be a good build and I'm following.

in 1:1 these parts will not interchange.
now, if they'd only produce the splayed valve small block head..............that would be cool!!!!!!

That's a good point that Dave mentioned too, and something they may work on to help us "mate" them to factory kit parts.
I am sure that you will get it seating correctly though with some careful manipulating.

Dave - for my edification, If I was going to my local speedshop to buy a BBC manifold, would I have to tell them it's 18 or 23 degrees? What BBC engines would each be found on?

then there the big block chevy..............
we could go on for days about this. if you want to know more. perhaps you should start a new thread on the subject. i'd be happy to give you input

I suppose for model building we have to deal with what we get in kits and/or aftermarket (except for a few here that have the ability to scratch build their components) and we'll only have to be concerned when we mix-match our parts - like Brodie is doing here. As long as we're discussing why these parts don't work, as Dave did, we're keeping in line with this thread, but I don't want to take away from this thread by getting away from the topic. I'll leave it up to others, if they want to delve further into this and start a new thread.

for instance i see TDR just made a new big block tunnel ram. beautiful piece. only thing is, it's only appropriate for chevy symmetrical port pro stock heads or maybe olds symmetrical port pro stock heads. it's not correct for the siamesed stock big block head. so,.......devil is all in the details. if you build for fun and none of this matters, that's fine. but,......if the details count then you need to know this stuff.

And for this reason, TDR offers the symmetrical port head for the big-block Chevrolet.............
Indeed, the devil is in the details....................

I was informed by TDR that the optional Symetric Port heads for the BBC are only different in the location of the intake ports and the location of the 'pre-drilled' bolt holes. Once the head is glued to the block, you don't see these differences.
It seems like if you want the TDR SBC or BBC induction to match the heads, you'd have to purchase the TDR engine that includes the heads and then you'd know it would all fit together. Otherwise it's a matter of making it fit.
Mark Johnson said he'll be issuing a SBC at some point down the road. He already has a BBC available.

that's very disappointing to hear, ted. for a number of reasons. a company that i believed to be committed to correct detail doesn't know the difference between a raised port small block chevy head and insists on calling it standard. the parts will never fit a standard head.......ever.
also the symmetrical port big block chevy head is not the same physical dimensions as standard bbc head. they are taller. so, the symetrical port manifold should NOT fit a standard head. the fact that it does leans to the fact something is incorrect.
i believe for the rather pricey parts that TDR produces. they should be correct to their 1:1 counterparts. to hear that they are drawing / producing generic "sorta close" parts really saddens me.

Dave - I'll find out, but I believe the stock SBC is just that - stock. I don't know where the raised port came in. I'm sorry if it was me that confused the issue. You mentioned the different degree valves and I wasn't sure where that fit in with the stock TDR engine.
Their BBC engine also starts out as stock and options are available to make it completely stock (single 4bbl, stock intake manifold and equal flow headers) to something more race ready (blown, dual turbos, tunnel ram dual quads, different headers). These 3D items are designed off of actual blue prints for sizing.
Their BBC 'performance heads', I've been told are only different from the stock heads as I described earlier. I need to look into these some more.
So we don't get off track and I'm looking for the wrong info, what is it you need to know and I'll get answers?

ted, i appreciate your effort but, there is no need to continue trying to straighten anything out. tony, has made it quite clear that accuracy or correctness doesn't matter to him or TDR and i quote:
".anyone that assumes that TDR product is correct or exact to the original is seriously mistaken and will be very disappointed"
for me, this just makes TDR more high priced parts. i'm sorry i tried to help straighten out an in-accuracy in their parts. obviously they are happy with it.

As far as the "inaccuracies" in their parts, I dont really see any, and if they do infact have some...who cares? This hobby is never going to produce 100% accurate parts and/or kits. It's our job to do the best we can, and TDR is no different. Their customer service is absolutely top notch and try to bring high-quality parts to the public so we can expand our builds and the hobby itself. I have only dealt with Tim from TDR, but he was very honest and helped me pick out the right materials and such. I give them an A+ for customer service...can't get much better than that!
