Now if edelbrock could just cast that same intake with a Buick flange it would satisfy a lot of frustrated TE headed owners
When I spoke with Mike at T/a about a year and a half ago and asked him why we couldn’t do this he said we could and it wouldn’t be that much work to do an intake so I have no idea why we haven’t done that already. All the dicking around you have to do with adapting the manifold and the welding it gets really expensive. Just one more thing to drive people away from running a Buick Who are looking at that kind of horse power level. I already have an SPX that is set up for Port fuel injection and ported so I didn’t want to invest more money in another intake. I epoxied the floor to match the track eliminator heads but since I’m building a street strip deal I don’t fully trust The epoxy for extended street use with pump gas so I ground out all the Epoxy and had it welded up
Thanks for posting Jim,keep the Dyno reports coming !I’m especially interested in the Tomahawk block with SRE oil pan set up with his louvered windage tray and T/a cover with stock oil pump gears versus high volume
Years back on my mid 9 second, 505 cube, 7000 RPM combo I tried both at the the track on the same day. Both Manifolds were prepped by the same person and I made the swap between time trials. I started with the Wildcat(SPX) and then the SP1. They ran the same ET and MPH...That being the case, I left the SP1 on and cashed out on the Wildcat.
I think Mike knows that the current SPX is really not the intake for these big HP/big Cid combos.. Even if you had an SPX that fit the TE heads, the porting required to max it out, and get it close to the performance level of the big mopar manifolds, would make that deal much, much more expensive than the adapted Mopar manfolds. The one on this motor is $1295. all done. In the world of custom aftermarket manifolds, that's peanuts. Unless you port an existing manifold yourself, your going to have closer to 2K in one of those. I have seen that bill from other customers. That was about the time I figured we needed to go a different way here. I am sure TA will eventually cast us a dedicated max effort single plane race manifold for the TE head, which will produce 800-900 HP out of the box... I will be happy to see it, as it will simplify my job considerably.
Ya, I think we have a handle on the wet sump Tomahawk oiling system stuff. Note the oil pressures on those dyno sheets. That's a wet sump/internal pickup/stock gear length/v-6-350 oil filter housing and wix filter setup. Exactly like a cast iron 455 engine. Simple, simple, simple. The key to making it work was my crank scraper/windage tray combo. I will put that in a new thread when I get time later this week.
Sure, This particular one was originally designed as a E-85 street motor, so we clipped the cam and compression on it a touch. It's actually designed to be about 750 HP, but this one has a very good set of CNC ported Stage 3 heads on it. It's a hyd roller cam grind, that we dropped in a set of Solid rollers with a tight lash setup, to insure he had all the rpm capability he needs, should he decide to run it hard. so it is not a really aggressive lobe profile. I like it for a low maintainence bracket motor.. this one should go years without touching it.... and it's going into a roller skate, so being fast enough won't be an issue.. Quick specs: 4.500 bore 4.365 Stroke 555 ci Heads flow 390/330 at .700 CNC port with our hand finishing. Cam is a 268/274 at .050 on a .425 lobe (Hyd roller profile) 12.8-1 compression GZ vacuum pump set up for 10-12" TSP/Edelbrock intake 1050 Dominator TSP/MSD crank trigger SRE Standard configuration wet sump Tomahawk pan/internal pickup TSP crank scraper/windage tray combo.

Would love to see a modern style EFI manifold. As far as the comparison of the SP2 versus the SPX the SP2 is heavy and prone to heat soak. For the 470-495 CI The SPX isn’t a bad deal if it was made to fit the track The track eliminator head. I cut the bottom out of mine to get rid of all the water cooling crap. there must’ve been a couple pounds of sand stuck in the bottom you would’ve never gotten it out and less you cut it open. With it being well ported it made good power and pulled to 7400 RPM no problem.
That's a neat engine Jim. Once I get this "going fast" out of my system, I will likely end up with something similar for bracket longevity
That’s what I’m building now.530CI tomahawk 11.5 compression pump gas EFI. Should make 750 HP.4L80 trans,4.10 gear.Get back to driving to the track!Can’t wait!
9s driven to the track, Tom? Sounds good....looking forward to seeing it in person. Is that verdemist green?
