I would like to speak with you in regards to your thoughts on an engine build up I am planning. I have a 95 Mustang Gt with a set of Thumper performance, ported/prepped/polished GT 40 cylinder heads with stainless steel valves, etc. E303 Ford MS cam, ported GT 40 lower intake and explorer upper in the car. It runs GREAT. I suspect it is over the 300 HP mark for sure.
I recently acquired a 95' Ford F150 with a 351W roller motor in it that I was planning on building up for my mustang should the 302 ever get tired.
I was planning on running the Thumper GT40 heads on the 351 to save on the extra cost of heads, lifters, rockers, etc.....but man was that ever met with a backlash from other guys. To them, the GT40's are junk! especially for a built 351……and don’t even think about using them on a 393 stroker!!
I was intending on rebuilding the 351 and either leaving it standard bore or stroking it to 393. Installing my GT 40’s on this motor with a good cam and matching edelbrock/trickflow/ or professional products lower and upper manifold since I can’t use my ported GT 40/explorer intake on the 351.
I have a few questions for you:
Is the stock internals of a 351 capable of handling HP and higher RPMs?
Will the Thumper performance ported/polished cylinder heads provide enough breathing for a 351?
What roller cam would you suggest to match up to this motor to go into a 95 Mustang GT with 3.55 richmond gears and 5spd?
I’d appreciate any insights. Any helps is appreciated. You sound like a very knowledgeable man and would value your opinion. I’d like to try and build this motor on a budget. This car is daily driver/street car and not a race/strip car. I would love to get 400HP and still be able to handle 5500 – 6000 RPM.
