They used to just make them for Chevy but now I believe they do for chrysler and ford. Anyone running one or hear any good things about them?

I have a retro fit one that for some reason someone put in my 89, i just pulled it, it had a aggressive idle and wound up good...it's for sale too

Is it the thumper or big thumper or the ***** thumper or whatever its called lol. What springs were required for it. Will it be a good with gt40ps and a carb? oh, and how much

mjr46

I suppose it'd be fine with gt-40 p's all I had were edelbrock performer 5.0 heads llightly ported, I'm just not into the lumpy idle on my street ride so that's why i PULLED IT, new they are 260.00.....130.00 and it's yours, also got an e-cam that has less than 2000 miles on it for 100.00......anyway here is the link to the thumper cam I have

oh it requires cca-986 springs...i ALSO have those too, 50.00 for them, they have less than 2000 miles of use also you may have to have your heads/spring pockets machined for use with dual springs, so best let a machinest do the set up/checking

Ok so 180 for the package, I get payed in to weeks so I will probobly have the money then and I will let you know. No PTV clearance issue with the stock shortblock?

mjr46

all items are up for sale on forums so first come first serve... yes 180.00 for the package will be fine if you make it.......and this had a stock bottom end and had edelbrock performer 5.0 heads with 1.90/1.60 valves and didn't have ptv issues but with any build you must always check
