Roberts 89 GT/U build 3400/3500 WOT-Parts

[TGP37]

Remember though the DR sets aren't available right now due to cost to hold inventory of a part that doesn't sell well. I'm still doing fine on my stock chryo treated set.

If it works just as good for moderate boost and an aggressive turbo cam, sure.

Crank machine work was free since it was a friend, but a shop shouldn't take any longer than an hour to do it.

I clearanced the front cover with hand tools just to ensure that it wont touch the chain... Took some time and made A LOT of aluminum chips... Reminded me of when I was porting my heads... lol But yeah that should be more than clear, I also touched the block where the main is since that was very close, and then just the larger oil galley plug I rounded the corner. I have .030 clearance in that area so it should be good.

When I did a test fit, the lower sprocket was far enough out for the chain to rub the front cover, so most of my work was done down by the seal end of the cover to ensure space.

When i installed my DRTC setup i did not have to cut the front cover at all, did have to grind just a little on the block to give the chain some more room to move around as it gets older and loose.
Did my own machine work on the crank, only took 1/2 hour to set up,cut and clean up.

Looks great Jon.
Maybe I should ship all my parts to you so you can build mine.....
How was it to get the crank scraper positioned correctly? Any trimming or filing required?
Out of curiosity, what did it run you to have the machine work done for the DR timing set?

[robert 1980]

I remember somewhere that it helped alittle with power.
Either way i feel better with it since people say they have snapped chains and damaged there engines.
Maybe it's the DRTC with the timing marks that helps more with a few extra poines not sure but we'll see

[3400-95-Modified]

I don't even know if the DR gives you any hp gain. As noted my chryo treated stock set is still holding up at least 3 years later.

Everything should be fully clearanced now for the DR set, I won't be back on this till Thursday then maybe I'll have the heads and timing cover on by then.

[robert 1980]

Figure the DRTC couldn't hurt, and a few extra poines also.
Yeah i wanted to go 10:5.1 Compression but im going to stay a 9:1
Maybe next year jon can help me with a 50 shot.lol

Come Jan-Feb, I'll be dropping some cash at wot-tech. Gonna man up and ditch this stock camshaft for a nice turbo cam w/ supporting head mods.....Seems like a double chain would be crucial for any aggressive cam profile with boost...sure don't want to break the chain and wreck havoc. And if the budget permits, forged pistons would rock.

Okay, thread jacking finished.......haha

[SappySE107]

The cover has to be clearanced. I might have a cover here, but if not, TCE has a jig to shave it inside.

[3400-95-Modified]

I'll let you know after tonight, I'm checking timing cover clearance.

[TGP37]

Those headers are impressive looking. The TCE double chain looks at home, I want one...lol

Is modifying the crank the only required mod to use a TCE double?

[3400-95-Modified]

Got the headers and the rings yesterday and did some work...







Quit a bit early, didn't want to be out all night. But here is what I got done so far.

I was re-reading the recipe for a hot 3x00 build and there was a note in there for a drop of blood from a psycho... Hope mine will do... lol




Short block with crank scraper installed.











going to finish up the timing components tomorrow or Wednesday night then clean up the head gasket surface and get the heads on... Then do the timing cover and get the oil pan on... well I hope to get that far

Those green bristle brushes work really well on the block, I think the Yellow would be good for aluminum since it can barely take paint off of the engine block.

[robert 1980]

I just saw a picture of the headers alittle while ago.Wow they look great and just like i said jon gets everything at onces.
lol

My mom works for the post office here. She says the way it's run there it's no wonder people go postal...

and why it's going bankrupt.
