I ran a custom ground crowder cam that had similar soecs, still have the card I can share if interested. Ran 11.25 on a bone stk low compression bottom end, port iron stage 1 heads, sp1, 950hp holley, ts headers, 4.10 gears, 4000 stall. Did not need that much stall, just was a spare motor slapped together when my 464 are a few bearings. I think it could had been faster with 2500 stall but I don't have a conveyer that low. Have video of it idling at 700ish if you send me a number I wI'll forward it to you......can't figure out how to load it on here
Do you need valve notches with the 70 style forged pistons? There not the low compression 71 and up style. Can they be fly cut? If so would a factory Stage 2 cam run as good or is the 107 run harder with ported heads and B4b?
I had to have my Speed-Pro version of those pistons cut for the KB-107. I learned the hard way back in the late 80's how not to trust a Speed Shop to do the job right just because they said that they worked on Alan Kulwicki's (NASCAR) engines. Ended up with that shop cutting them wrong a second time, .... and they ended up paying me for the pistons they ruined and then ultimately having Mike at T/A cut a whole new set of them. I can't speak for Mike but I recently had him re-cut a set of Ross Racing Pistons. He may fly cut them for you, ... but you would have to call him to confirm. That whole incident is what catapulted me into buying all my own measuring instruments and learning to perform all my own engine building/design, ...... (everything less actual machine work). So even though that whole ordeal was a hassle, ... it paid off in the long run! Larry
anyone running a C-107 with TA heads or high compression ratio ones and using the MSD setup? The C-107 was always a hairy idle with stock 10.5 stock iron heads but now with TA heads and higher compression ratio I am having trouble dialing in it where I can get it to start, idle half decent and still pull at high speeds. Was still running stock points distributor since it was build a while back and from what I read the MSD set up helps with these kind of problems
We have a 107HL in a 13.6 to 1 with TA Street Eliminator heads, it's on e85 with a 950hp it starts up with two pumps of the pedal and idles on its own at 1200 with 18° initial 34 total. On the dyno with iron heads , intake and Qjet it made peak HP at 5400, but as Gary mentioned it starts to fall off at 5k you can feel it laboring,..but from 2k to 4500 with a 410 gear it's SUPER fun and pulls wicked, hope it will go 118+ this coming season
here is a video of my friends stage 2 motor with the window rattler and one of one circle track headers!
MSB 6A ignition box and billet distributor did the trick, car starts easy and idles good (well lumpy good) and has never run better, didnt have to play much with springs and bushing but can probably dial it in better. The new C-107 sounds good running through headers and cherry bombs (yep from the 1980's when I first did the engine) need to update with new mufflers and full exhaust
Thanks for all the input guys! I lost my password for what seems like forever, I have however, purchased the TA 290 HL cam. It sounds like what I want for my car.
