Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
With this build, are you good to go using the stock cam that comes in that motor? Also, what about oil pans? Can you use whats on there or can you use the syty pan? I may be doing this in the VERY near future as I think I may have popped another motor and thought this would be the way to go so at the very least to have a nice buildable platforn for the future. How much boost can be run on 91? If anyone can answer these questions ild appreciate it. E, are you using any of the 3 cams on 91? If so, how are they working out and how much are they selling for if youre even selling them?

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
I haven't got around to this. When I had time this past spring (and looking for a job, working only part time), my dog had a couple medical emergency's. When I had a good paying job, I didn't have time. I would like ot start working on this swap again, but tis been damn cold or something else has popped up. I can give you the info E Rue has given to me.
Oil Pan - use the later cast oil pan and have a bung welded on it for the turbo oil return line. E- used the stock SYTy oil pan and he said it was pain in the ass to get it to stop leaking. I think I am using a male AN-10 bung for the oil return line, I am using Turbo Time braided oil return lines as well. E-mention to me not to weld the bung in the stock oil return position, because it will hit the motor mount. I am having it weld about 6" rearward. This might just have to do with the braid line though.
Cam - use the later cam, it has far more lift .415/.429 than the stocker does .357/.390 and it has more duration on the intake as well. If it fits, I am going to use a L35 cam, which has even more duration/lift. Anyway, the later cam is leaps and bounds above the stock SyTy cam.
I can't comment on 91 Octane, but I was planning on lower my boost 3-4 PSI on pump gas to start with to compensate for the higher compression. I am also going to Alky so I can run some pretty high pressure, I am hoping ot run 17-18 regularly and push it at teh track with 20+ psi.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
i ran 10psi for break-in on pump gas and am up to about 15-18 psi with meth, still has a bit left, spool up is awesome, milage is still decent too, got 18mpg going 75mph with 400 lbs of gear in the back of the ty.
just reference this chart to keep desired cylinder pressures with higher compression, might be suprised to see how high the boosted compressions of the engines we run A 20psi and 8.5-1 comp.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
Im going this route for sure when my motor goes. Sounds like fun. I found out my motor is ok today, my balancer bold and crank pulley bolts were fallingout making a knocking sound. Still, I can get a 50-60k mile 2003+ for $795 here at a local yard. I think its worth it. Im sure htere are yards elsewhere that sell them cheaper but when you factor in getting it here it would cost me the same. Ive been curious about this for a long itme and I am going to try and acquire the motor this summer so I can get the conversion done before the end of summer. Hopefully by June/July and get my alky kit going. Pinks will be here in August, I hope to do this by then.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
the ballance shaft custom cams are going for about $325ish and vary in rpm range. they are fast ramp turbo specific with high lift.
im still running my motor and testing out different things......i run 15psi daily and 100% E85. i ran into issues with cold start, when its below freezing outside, so iv dropped back to 75% E85 till winter blows over. working on some cool tricks with electronics to allow cranking in cold weather. should have some cool new stuff available soon. E85 is the future.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
Nice. I cant justify E85 right now. We have a total of two stations in this whole town that sell it and its more than premium. Ild rather use alky on 91. When I do this Ill hit you up for a cam. Would these cams work ok with lowered compression? Depending on what kind of funds I end up with when I do this I may end up tearing it down and lowering it. Unless its viewed as a better deal to have it higher.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
Pink's all out? or are you putting the ty up for a pinks race???
Also E-rue what injectors are you running with this combo? I am truly interested in trying e-85. But no-one has really tried it but you... Any pointers???

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
The compression on the Vortec really isn't that high (I have seen 9.0:1, but I think its closer to 9.3:1 to as high as 9.5:1). Most of the SyTy rebuilds with JE Piston end up at 8.6:1- 8.7:1 once the block and head have been deck.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
You dont race for pinks on all out. Atleast not last time I watched it. I wont get into the class chosen anyway, just want to make a decent impression. On CRN(local racing forum), there is a whole thread abotu it and how they should choose the 9/10's classs just to hsow that they can do it in our altitude. Personally, Im kinda hoping they see a bunch of SYTY's and want to see htem in the end but iM sure that wont happen.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
A lot of people run E85. I hear nothing but good things about it performance wise but the problems i hear about steer me away from it. You have to have nearly twice the injector to run it and you use 40-50% more than you would normal gas. Sounds like a huge PITA to me especially for what is costs.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
Then Ill do it that wya, maybe just throw the cam in there. I like this idea because even though its kind of cheap, you have everything there that you would want in the future. Im not sure if the rods are a whole lot better than our stock rods but Im at 203k on stock rods so the beetter rod in the later 4.3 Im sure would suit me fine anyway.

Re: Using a Vortec Engine in SyTy (was budget engine rebuild)
If your doing a cam, you will also need GM's service bulletin for the timing chain rattle. (You may need this anyways)
The part numbers are
12458911 Chain Kit
89017257 Tensioner
89017259 Cover Kit, which I think include tge oil pan gasket as well.
They cost about $225 through a discount dealer.
Also you will want to use the later style starter when you convert over as well or you will end up with flywheel zing when you start the motor.
