This question has actually been beat come death. Through a safe tune, a 302 can last countless many years at 450-500 RWHP. And also that is at the track obtaining beat. It"ll critical much longer with street miles.Also this number is based upon my experience, im sure others will certainly say that someone else"s buddys friend cousin blew theirs up making 400 hp.

yeah i figured that has. .. However every year 302 to be rated at a various hp. And 1983 contrasted to a 1993 i figured would certainly be a whole various story. Ns was spring for about 350-400 horse power. Nothing too crazy. What would certainly be a great set up for this?
i have actually been looking in ~ the paxton centri. And the weiand 174 .. Seems favor the weiand will need a new hood. Yet is around 1.5k cheaper 보다 the paxton. Have actually not find any kind of turbo kit for a carbed set up.

The power ratings adjusted year come year due to alters in cams, heads, compression, etc. The blocks are very, very similar in what castle will take care of from the 80"s ~ above up.
83 5.0 GT. Faster than the looks! 10:1 (or simply over) 306, Motorsport a332 cam, 140A alt, t5 conv, 8.8 w/ 3.27"s, Edel rpm, alum rad, an extremely worked e7"s, Holley SA carb, etc...

anybody ever heard of those bars that bolt into the entry valley?? I witnessed them ~ above HP tv for a 5.0. Castle bolt under the lower intake, come reinforce the engine indigenous twisting and also cracking in half. I"m wondering if anyone has ever run castle before, and also with what success.

I"ve checked out pics on an additional web site of a 5.0 block v reinforced lifter valley and bottom finish that still cracked in half. The girdles just organized the piece together....didn"t keep it from breaking.
the block is the weakest attach regardless of mileage. As shown already, a share 302 block (all years - even the touted mexican block) will host 450-550 hp v a good tune. It might last for years yet the weak link is the block and also not the internals. At this strength level be mindful that you room on borrowed time.
There is no magical number. A well competent 5.0 builder can acquire 600-700 HP out of the stock block. There"s so much an ext involved in what causes a block come fail 보다 mere HP numbers. What I"ve heard/read is the no one"s obtained a block to last more than 30 minutes end 800 HP though.
"The fact that "replica" is written down the side of your gun, and also "Desert Eagle suggest five oh" is written on the side of mine, have to precipitate her balls into shrinking!"
ok awesome guy .. Thanks.. So what set up need to i watch into? i dont want to go into building the block.. Or what not.. What power adders will be a reasonable set up? turbo? centri?
Have you thought of act a stroker kit for her block?It should cost a bit much less than your budget and also possibly be much safer than supercharging.I see many 347 longblocks dynoed at more than 400HP & TQ.
1985GT, FRPP Y heads, e303, Edelbrock intake, 3.55 8.8, Magnaflow exhaust w/ X-pipe, SN95 Cobra brakes, coil-over suspension, Need assist w/ SN95 Brake upgrades or locating difficult to uncover parts?
Have you believed of law a stroker kit for your block?It should price a bit less than her budget and possibly be safer than supercharging.I see plenty of 347 longblocks dynoed at an ext than 400HP & TQ.
i am no mechanically savy.. Therefore what all would i need to construct a N/A beast choose that? a 347 stroker sounds nice.
All terrific info, and true. I have seen the break-up block at just over 500 hp. It is among those thing you simply can"t believe. One point I should add, If you space on a budget and also can"t afford a brand-new ford block, always go together old together you can. My machinist told me the older blocks were far better alloy. Much more nickel, if storage serves me. Also, the cores are cleared up from more heating and also cooling cycles. Check the subject on the 351w i m sorry is a great and stronger option. Remember there is no replacement because that displacement! A 351 will bolt in as easily as a 302, and you have the right to safely and also reliably stroke that to 400 cubes and drive it anywhere. Great luck, Kerry

I"ve seen few of the dare up she well north of the on a stock block (girdled and also chamfered the course) yet handling an ext power no one the less. Blower cars deserve to handle it if they are tuned well, castle don"t check out the abuse all the time, prefer a high compresion stroker would, but like said"if they are tuned well"
That is a myth. Talk to Foxchassis. The blocks have actually been tested to prove otherwise.He will certainly tell friend that:
Hencho en Mexico 302 blocks are far better than "later" Cleveland-cast 302 blocks because the key bulkheads are thicker. The "higher nickel content" is a myth. I understand first-hand that someone who tested one of those blocks with a spectrometer. And John Vermeersch of total Performance (if you referred to as the FRPP hotline, you obtain his shop in Clinton Township, MI) had actually an article in among the Mustang rags (Super Ford?) a few years earlier dispelling the myth. John was one ex-Ford engineer, if that makes a difference to anyone.The later 302 blocks are undoubtedly lighter and that"s due to the fact that they have actually been thinned-out not just in the key bulkhead area yet the cylinder wall surface thickness as well. Not sure about the thickness of the deck.
the block is the weakest link regardless that mileage. As shown already, a stock 302 block (all year - even the touted mexican block) will organize 450-550 hp through a good tune. It might last because that years but the weak link is the block and not the internals. In ~ this strength level be mindful that you room on obtained time.
wow thats awesome! for this reason u r tellin me ns can get 450-500 hp native my share block. A great tune native a supercharger ur sayin...wouldnt a 347 stroker kit be a lil much more wise than superchargin" the sucker to gain that kinda hp???????????

yea the sounds yes, really nice...i recognize its displacement and also all and also all my various other mods would bolt directly in..but ns am curious to understand what and how lot $$ it would certainly take,not to point out time and money. Ns can acquire a host of a cherry picker,but no $$$ for a kit

I damaged a stock block make "only" 313 in ~ the wheels however I routinely shifted at 6600 and a few launches at 7000 rpm. That motor lasted 5 seasons and also close come 100k miles. ~ above the other hand, a good friend had a share shortblock 93 that made 590 come the wheels and stayed with each other for years. An additional aquantance do 635 through an explorer motor last summer. Just how long will certainly it organize up is up to the god of speed and also luck. A well assumed out stockish motor will certainly last a great amount the time and also take a beating as long as girlfriend dont gain greedy through the power or rpms. My existing motor has put down 340 in ~ the wheels through a C4 and Im around to adjust back to a 5 speed for the fun factor. Id like to check out 450-500 at the wheels next year. I will try to resist adding more boost tho.
