Voodoo cam 350
This creates more overlap between exhaust and intake events and more “cool” performance sound. The Thumpr line delivers true high performance engine sound by “tightening” the lobe separation angle of the camshaft. The basic science behind the Thumpr Cams is not a new one. I think the crank failure in the turbo car is related to the ATI damper I had on the car. They were the “1500 hp rated “ blocks with I beams and ARP hardware thought out. īoth MMR blocks now in the cars are identical. I am not sure if the turbo car will benefit as much from the high lift cams since I won’t be spinning it that high. The heads also already have the MMR valve springs but I wonder about them since that’s what is supposed to be in the motor now seeing float (might be a reason to go with the GT heads which will have PAC springs). If I use the GT 350 heads I will have to use the GT cams due to the wear pattern. One of the reasons I chose to use the Gen 2 (MA) block is so I can use the 12 mm head studs. I am looking forward to the RPG built block going in the Hellion car. Unfortunately since it started off as 15 block I can only use the 11 mm studs (.L&M could have done a conversion when the block is bare ) Springs are stock but I was not having valve float in the blower car and RPG says they are 15% stiffer than stock GT cams. I also chose to use the upgraded phasers and lifters. There was additional expense using those cams as you know since you have to use the OEM GT 350 followers. I figure the blower car would benefit more from the cams since the gains will be mostly at higher rpm. I used the “Voodoo” or GT 350 spec cams in the long block going in the KB car. I am hoping the longer 12 mm head studs will help with the head lift. I will be using either GT 350 heads/MMR springs /GT cams (if an old pair that has scoring can be fixed ) or GT heads with PAC springs. Will at Whipple is building me a replacement 5.2 block using the updated Gen 2 5.2L block for that car. I am hopefully but doubt I will be able to salvage any parts. I won’t be pulling the motor till I have the replacement ready. Ĭrank broke on what was to be the last pull. It was also lifting the heads psi and maybe had valve float but still made 1100 whp. I saw some big gains over 7000 rpm with the GT 350 intake over the 11-14 intake I had before (the 15-17 intake won’t fit the GT 350 heads ) It had gone (6R80) and was sure it had an 8 second pass in it. That motor had about the same miles and dyno passes. I had the same MMR block in my Hellion car (also GT 350 heads/stock GT cams ) and broke the crank on the dyno testing the GT 350 intake I had just swapped. Probably just going to visually inspect and deck the head and block and reassemble with new head studs. I will surely post up pics if I tear the block down. Only 3 dyno pulls since I swapped heads but no passes īest so far was 10.0 144 but it’s trapped 148 mph.

Most passes were at local strip that kicks me out (or gives me warning ) after first or second pass. MMR motor had about 10 passes and may be 2000 street miles in 2 years ,mostly short trips for street logs and a few 100 mlle trips to a drag strip that lets me run 9’s without hassle. With hind sight I should probably have started off with Gen 5.2 block (sleeved or unsleeved) since it uses 12 mm bolts /studs which would have helped the head lift issuesĬrank is coyote.

I am sure I will have it on the dyno to get it dialed in since the cams will need a different tune. Car will probably be for sale then if I can resist racing(drag) it again. I am hoping to get a few passes(hopefully a 9 second with the Magnum XL ) out of it before I swap in the new motor. Ĭar now makes 950-1000 rwhp with 18 psi but is lifting the heads on the dyno. The motor in it now has an MMR built/sleveve 5.2 and started off with GT 350 heads(stock GT cams ) but swapped to GT heads when I was replacing a blown head gasket and found the heads hadsome scoring. It’s a replacement motor for the one currently in one of my 15 GT’s with 3.2 KB Of course oil pump with billet gears /crank sprocket and GT oil pan. I used the “upgraded” phasers and lifters and OEM rocker arms. The GT 350 heads were cleaned but not ported and assembled with the Ford performance GT 350 spec cams. I am not sure if the pistons were “GT 350 specific” I started with a brand new 15 GT block, BES sleeved to 3.7 bore and built with Ross 11.1 pistons and Manley rods. I have just had my CPC 5.2 long block assembled.
