You do not need some custom convertor. All you need to do is go to Trishield Performance that is run by Jim Wise and he has convertors that he guarantees for life. There is a hole new article on what he has within this site. We have one person here that did not like the 284 not people that have used it. I would say a 2200 stall would work just fine. The cam will be just fine but will be slightly on the racing side but not a hole lot. TORQUED455 sounds like he has built some motors so it looks like he knows what he is doing.
2200 if he had the gearing of a 200r4 with 3.73 rear end. 2200 is more for stock cam and 212 cam. He doesn't need a custom but if he was looking for the best parts to make his car run the best time then that would be optimal. What makes me wonder is that people pick other cams when the 212 has proven that it can make 360 HP and 400 plus lbs of torque thru most of the rpm range by Jim Wiese. It works well with low or hi compression. Yet most seem to overcam . been there. Wasted money.
It doesn't look like he looking for the best of anything with this build. He is going to need to run the biggest cam he can in a high compression cast piston engine to get the dynamic compression down enough to not detonate. Its funny here, the BBB guys say the 4032 forged pitons aren't good enough for a 455 performance build and the sbb 350 guys say they're to good. LOL! Derek
I understand he isn't looking for the best. But after running the 118 can,310 cam, and that mutha thumper from comp cams and finding they didn't fit my combo , just hope to direct others on to a better build. Although I kinda think if the 380 was n/a the big cubes could handle that 310 cam. As far as BBB guys running 4032 pistons, maybe they should not overtime them things
They shouldn't over time them no matter what piston they are running wouldn't you think? Maybe he should look at the Crower level 2 cam, those seem to run very good as well. Derek
So now that all decisions have been made, .030 over, new Pistons, .020 gaskets and the 288 cam. I'm looking at headers, is there any reason to got dougs headers over ta performance headers? They are both approx the same cost @$450
I'm sure you know to jet that up abit as ethanol leans fuel out and these cars where built before then added that stuff to fuel. Up the secondary rods and hangers too. That engine should be pretty stout. I'm going to guess at least a 300 HP engine. That's being conservative.
Engine in! Runs great sounds awesome. Strong acceleration and no stumble at all super smooth. Combination of the cam, converter and the carb mods work great together. Thanks so much bob!!!:3gears:
Glad you are happy. I was pleasantly surprised that with the low-end power given all of the bad experiences people have with the 284 cam. Has a nice rumble and pulls extremely well! To sum-up Marc's build, it is the original 72 350, calculated 9.53:1 cr, .030 over 340 Pistons, steel head gaskets, original untouched intake and routine valve job on heads, no block decking, just enough off the heads to clean them up, TA 284 cam, stock valve train, original Quadrejet, Doug's headers, Hughes 2800 stall converter and 3.42 gears. Nothing trick, runs exceptionally well, 93 octane and no vacuum problems for the power brakes. I thought about advancing the cam 4 degrees but put it in at 106 which is where TA recommended I think.
I never took that measurement. The volume of the piston dish to the deck was 23cc. I confirmed that the cam is in @ 106.
After all the crying everyone did about this combo and 284 cam not working, it looks like it worked really well. Did it all with 9.5 compression. Just as I thought it would. Next up the track?
